    Background: We conducted a cross-sectional study of residents within and outside Fukushima Prefecture to clarify their perceptions of the need for smartphone applications (apps) for explaining exposure doses. The results will lead to more effective methods for identifying target groups for future app development by researchers and municipalities, which will promote residents’ understanding of radiological situations.Materials and Methods: In November 2019, 400 people in Fukushima Prefecture and 400 people outside were surveyed via a web-based questionnaire. In addition to basic characteristics, survey items included concerns about radiation levels and intention to use a smartphone app to keep track of exposure. The analysis was conducted by stratifying responses in each region and then cross-tabulating responses to concerns about radiation levels and intention to use an app by demographic variables. The intention to use an app was analyzed by binomial logistic regression analysis. Text-mining analyses were conducted in KH Coder software.Results and Discussion: Outside Fukushima Prefecture, concerns about the medical exposure of women to radiation exceeded 30%. Within the prefecture, the medical exposure of women, purchasing food products, and consumption of own-grown food were the main concerns. Within the prefecture, having children under the age of 18, the experience of measurement, and having experience of evacuation were significantly related to the intention to use an app.Conclusion: Regional and individual differences were evident. Since respondents differ, it is necessary to develop and promote app use in accordance with their needs and with phases of reconstruction. We expect that a suitable app will not only collect data but also connect local service providers and residents, while protecting personal information.

    We propose a simple algorithmic method of spectral determination method (SDM) for gamma-ray determination, which is based on the first principle that a gamma-ray spectrum obtained for a sample is a linear superposition of individual spectra of the radioactive nuclides included in the sample. The SDM treats the whole spectrum including peaks and a continuum background due to Compton scattering and does not need the peak analysis, which has been most conventionally used so far. The SDM was demonstrated by using two separate detector setups with a NaI detector or a Ge detector. The first experiment utilized six mixed standard sources. The determination accuracy of the SDM has turned out to be reasonable as compared with that of the peak analysis. In the next experiment for standard samples of JSAC0731 and JSAC0785, both Ge and NaI results show that the deviation of the SDM results from the certified values is within reasonable uncertainties for C-137 and Cs-134. The present study demonstrates that the SDM is a reliable gamma-ray determination method with a simple procedure.

    Charged particle activation analysis (CPAA) is a rapid method with high accuracy which can analyze multi-elements simultaneously. Since multiple gamma-ray detection method is expected to improve the detection efficiency and the signal-to-noise ratio, we study what design of the gamma-ray detector array is the most suitable for CPAA. We take up four design candidates and investigated the responses by the radiation simulation code Geant 4. From the results, we have deduced the best design with 5 germanium detectors in close geometry. By inspecting the sensitivity in CPAA, the method is proved to be useful and applicable to 116 nuclides.

    © 2015 The Physical Society of Japan. We successfully measured muonic X-rays of cosmic-ray muons stopped in Al and Fe targets. In order to identify the events that incoming cosmic-ray muons were stopped in the targets, a coincidence and anticoincidence system of three plastic scintillators was used. The X-rays associated with the atomic muon captures were measured with germanium detectors. Measurements using the Al and Fe targets were carried out for 33 and 16 days, respectively. A sufficient number of muonic X-ray events for identifying the elemental compositions of the target materials were clearly observed. This technique provides a means of nondestructive elemental analysis that does not require the use of particle accelerators.

    Proton computed tomography (CT) is an imaging technique using a high-energy proton beam penetrating the human body and shows promise for improving the quality of cancer therapy with high-energy particle beams because more accurate electron density distribution measurements can be achieved with proton CT. The deterioration of the spatial resolution owing to multiple Coulomb scattering is, however, a crucial issue. The control of the radiation dose and the long exposure time are also problems to be solved. We have developed a prototype system for proton CT with a silicon strip detector and performed a beam test for imaging. The distribution of the electron density has been measured precisely. We also demonstrated an improvement in spatial resolution by reconstructing the proton trajectory. A spatial resolution of 045 mm is achieved for a 25-mm-thick polyethylene object. This will be a useful result for upgrading proton CT application for practical use. (C) 2013 Elsevier B.V. All rights reserved.

    Proton computed tomography (CT) is an imaging technique using a high-energy proton beam penetrating the human body and shows promise for improving the quality of cancer therapy with high-energy particle beams because more accurate electron density distribution measurements and in-situ positioning can be achieved with proton CT. The deterioration of the spatial resolution owing to multiple Coulomb scattering is saved by reconstructing the proton trajectory. We have developed a prototype system for proton CT and demonstrate a precise measurement of electron density and an improvement in spatial resolution. In order to control of the radiation dose and reduce the exposure time for imaging, the precise position detector should work with very high rate (a few MHz). We have developed high speed tracker with large area silicon strip detector, Amplifier-Shaper-Discriminator LSI, which was developed for drift chamber readout at high energy physics experiment, and FPGA. We report the performance of the tracker evaluated with very high intensity proton beam for the cancer therapy.

    Dynamic nuclear self-polarization (DYNASP) is a phenomenon observed in III-V semiconductors. When electrons of the valence band of a semiconductor are optically excited to the conduction band, a relaxation process of the conduction electrons induces a large nuclear polarization to suddenly occur below a critical temperature. This mechanism is useful for nuclear magnetic moment measurements of unstable nuclei implanted in semiconductors. (C) 2013 Elsevier B.V. All rights reserved.

    The gamma-radiation has been investigated for Ni-63 produced by cold neutron capture in an enriched Ni-62 sample. The 315 gamma-rays produced were placed in a Ni-63 level scheme, in which 272 placements are new. We determined the excitation energies with 0.2-0.8 keV error and the branching ratios of 62 bound levels in Ni-63, including 30 new levels. The Q-value of the Ni-62(n, gamma)Ni-63 reaction amounts to 6837.75 +/- 0.18 keV. A large-scale shell-model calculation was performed that included the four single-particle orbits of 0f(7/2), 1p(3/2), 0f(5/2), and 1p(1/2), assuming an inert Ca-40 core for negative-parity states, and those of 1p(3/2), 0f(5/2), 1p(1/2), and 0g(9/2), assuming a Ni-56 core for positive-parity states. The energies of the low-lying Ni-63 states were successfully reproduced. A mean-field statistical-model calculation was also performed by using a self-consistent interaction between the Hartree-Fock + Bardeen-Cooper-Schrieffer method and the statistical calculation. The calculation result is consistent with the experimental level density of Ni-63.

    The 4 pi Ge spectrometer composed of 22-30 Ge detectors was developed, and it has been used to study neutron capture reactions with a neutron time-of-flight (TOF) technique. Since the distances between the sample position and the Ge detectors are variable, it can be used as a multifunctional spectrometer. At first, it was used as a sum energy spectrometer, and resonances in (nat)Ag were identified as those of (107)Ag or (109)Ag. In second, it was used to deduce gamma-ray intensity distribution for each resonance, and the results for (238)U were presented. In third, it was used to measure neutron capture cross sections of minor actinides and fission products at the electron linear accerelator facility of KURRI and at the accurate neutron-nucleus reaction measurement instrument (ANNRI) in MLF of J-PARC. The preliminary results are discussed mainly based on measurements of neutron capture cross section for (241)Am, together with related techniques.

    Lattice nuclei of III-V type semiconductors can be self-polarized through the contact hyperfine interaction with artificially excited conduction electrons at extremely low temperatures. In the self-polarization process, a positive feedback between the nuclear magnetization and the expansion of the energy splitting of the conduction electron states due to this nuclear magnetization takes an essential role. Extending the original theoretical work on the self-polarization with linearly polarized (LP) light by Dyakonov and Perel,(1) we examined the effect of the circularly polarized (CP) light on the phenomenon of the nuclear self-polarization. While no polarization is obtained with LP light above the critical temperature, the nuclear polarization is enhanced also above the critical temperatures with CP light. More important finding in the application of CP light is that the direction of the nuclear polarization can be controlled by the orientation of the excited conduction-electron polarization, which is easily manipulated by changing the degree of polarization of the excitation light. Related to this polarization change, it is also remarked that the nuclear polarization shows a hysteresis phenomenon below the critical temperature when the degree of the electron polarization is swept up and down.

    Medium-spin states of Ge-70 have been studied via the Ni-60(C-12,2p gamma)Ge-70 reaction at 45 MeV. The ground-state band and the second 0(+) band have been extended to the 12(+) and 8(+) states, respectively. Two negative-parity bands, one of which has a coupled structure and the other has a decoupled structure, have been observed additionally. Although the latter decoupled structure was known up to the (21(-)) state from a previous experiment, the part of the level scheme up to the 15(-) state has been largely modified by the present experiment. Backbendings observed in the positive- and negative-parity yrast bands have been compared with those of the neighboring even Ge isotopes. The experimental level structure has been compared with the shell-model calculations in the model space (2p(3/2), 1f(5/2), 2(p1/2), 1g(9/2)) employing two kinds of effective interactions, one of which is an extended P + QQ interaction with monopole interactions and the other is developed from a renormalized G matrix. Microscopic structures of the observed bands have been discussed with the help of the shell-model calculations.

    High spin states of Dy-144 have been studied through in-beam gamma-ray spectroscopy by using the reaction Mo-92(Fe-56,2p2n). It has been found that the continuation of the ground-state band forks into three Delta I=2 bands above the 8(+) state. This forking has been attributed to the alignments of pi h(11/2)(2) or nu h(11/2)(-2) configurations with the help of the systematics in neighboring nuclei. Additionally a negative-parity sideband of Delta I=2 cascades has been observed to start from the 5((-)) state and continue to a dipole band above the (13(-)) state through another negative-parity sideband of Delta I=2 cascades in between. These structures have been discussed from the viewpoint of a competition between "Magnetic Rotation" and "Anti-magnetic Rotation" based on a classical particles-plus-rotor model.</p>.

    The Zr isotopes between Zr-90 and Zr-96 are expected to be spherical based on the almost complete subsbell closures at Z=40 and N=50,56. On the other hand, they have low-lying 3(-) states and show the characteristics of low frequency octupole oscillation which arise as a superposition of particle-hole excitations. A 380 MeV Zr-94 beam from the tandem accelerator at the Japan Atomic Energy Agency (JAEA) was excited on a self-supporting Pb-nat target. The gamma-ray detector array GEMINI-II was used to detect deexcitation gamma rays. The scattered beam (Zr-94) was detected with a position-sensitive particle detector system. The gamma-ray intensities were used as an input to the least-squares search code GOSIA to determine the E3 matrix element of the first 3(-) excited state of Zr-94. The B(E3;0(+)-> 3(-)) value of 0.21(6) e(2)b(3) in Zr-94 has been obtained by Coulomb excitation experiment.

    Low-energy photons produced by the Compton scattering from hydrogen increase the background in the lower-energy region of the gamma-ray spectrum. This results in an increase in the detection limit for trace elements. In multiple photon detection prompt gamma-ray analysis (MPGA), only those elements that simultaneously emit two or more prompt gamma-rays, which have cascade relation and are emitted within a short interval, can be measured. Therefore, the influence of hydrogen can be reduced. In this study, standard polymer and food samples are measured. The hydrogen background is reduced in MPGA.

    A neutron beam line for multiple prompt gamma-ray analysis was constructed at the Japan Atomic Energy Agency. A detector system for the MPGA was constructed at the C2-3-2 beam line in January 2005. It comprised eight (upgraded in March 2007) clover Ge detectors with a BGO Compton suppressor. High efficiency detector system provides an advantage in terms of the detection limit of MPGA when compared to the result of PGA. The supermirror neutron bender was improved and a supermirror neutron guide was installed upstream of the sample position.

    The excited states of the doubly odd nucleus I-118 have been studied by using in-beam gamma-ray spectroscopy with the Cd-110(C-12, p3n) reaction at E-lab = 80 MeV. We have established several multi-quasi particle states associated with different proton and neutron quasiparticle configurations. A I-pi = 14(-) level at 2561 keV was newly observed and found to be associated with the pi h(11/2)nu d(5/2) configuration coupled to a pair of protons in the g(7/2) orbital. TRS calculations for the 14(-) level indicated a favored oblate state based on the fully aligned four-quasiparticle pi[h(11/2)(g(7/2))(2)](23/2)-nu[d(5/2)](5/2+) configuration. Another energetically favored state I-pi = 24(-) at 6216 keV could be interpreted as a noncollective oblate state from the fully aligned six-quasiparicle pi[h(11/2)(g(7/2))(2)](23/2)-nu[d(5/2)(h(11/2))(2)](25/2+) configuration. No Delta = 1 side band of the same parity as the pi h(11/2)nu h(11/2) band was observed while a side band built on the pi g(9/2 nu)h(11/2) configuration was considered to be caused by the gamma vibration coupling.

    Neutron capture cross sections of minor actinides and long-lived fission products are important for the R&D of innovative nuclear reactors. However, those data are rather poor both in quality and in quantity at present. Thus, we have started projects for neutron cross section measurements. We have constructed an 4 pi Ge spectrometer consisting of Ge crystals and BGO shields. The neutron cross section measurements have been done at KURRI electron linac and JAEA JRR-3 facilities, which will be extended at the high-intensity neutron source at J-PARC.

    We have evaluated the performance of our new data acquisition system (DAQ), which utilizes digital signal processing techniques and was developed for a 4 pi Ge spectrometer. The total energy resolution of this system was 2.5 keV in FWHM for 1.33-MeV gamma rays and 16.4 keV in FWHM for 10.83-MeV prompt gamma rays. The time resolution of timing signals, which are used for the measurements of coincident gamma rays, was 120 ns in FWHM. Those values fulfilled our requirements for the DAQ. A method of dead time correction with this system was also developed.

A new Ge detector system for multiple prompt gamma-ray analysis (MPGA) was constructed at the neutron guide-hall of the JRR-3M reactor of the Japan Atomic Energy Agency (JAEA). The first demonstration of this system was given with a plastic sample containing traces of cadmium. The quantification limit of cadmium in a plastic sample was found to be about 0.1 ppm.

    Recycled steel products demands a new technique for determining tramp elements in steel. In this paper, As and Sb in iron certified reference materials were determined by neutron activation analysis with the multiple gamma-ray detection method. The determined values are in good agreement with certified and reference values. The lower determination limits (LDL) for As and Sb in high purity iron are 0.012 and 0.0025 ppm, respectively. As the demanded LDL for As and Sb is 0.1 ppm, the method described in this work is suitable for determining As and Sb in recycled steel.

    The Cd concentration in food is a public concern related to the human health. In order to remove Cd-polluted food, the development and validation of a rapid and sensitive method of Cd analysis is required. By applying the multiple gamma-ray detection method to prompt gamma-ray analysis (PGA). the influence from nuclei which emit only one prompt gamma-ray at a time at every neutron capture reaction can be reduced. therefore the quantification limit of Cd is improved significantly. The limit of Cd contained in rice in the case of MPGA was evaluated. and under our proposed experimental conditions, it may be possible to quantify Cd content in rice to within 0.2 ppm in 10 min.

    We are developing a 4 pi Ge-spectrometer for the measurement of neutron capture cross sections of minor actinides. The 4 pi Ge-spectrometer consists of Ge detectors that cover a large solid angle of a sample; the spectrometer has high efficiency and good energy resolution for gamma-ray detection. This feature enables us to discriminate desired events from backgrounds based on the measurement of total excitation energy following the neutron capture reaction. In this work, we determined an optimal configuration and evaluated performances of 4 pi Ge-spectrometer using a Geant4 simulation. From comparison of performances, two configurations that have uniform count rates or a high efficiency were determined. Therefore one of the two configurations is used properly to reduce an experimental error for the neutron capture cross section. Further simulations were made with a full geometry including BGO shields; absolute efficiency for the high-efficiency configuration was estimated to be 15% for a 1-MeV gamma ray.

    Most of nuclei emit two or more prompt gamma rays in the neutron capture reaction. In multiple prompt gamma-ray analysis (MPGA), the gamma rays are simultaneously measured by two or more sets of gamma-ray detectors; these gamma rays are reduced to a pair of two prompt gamma rays, and it is added to the two-dimensional spectrum, which sets two energy axes. A gamma-ray peak corresponding to the pair of gamma rays that are emitted simultaneously will appear on the two-dimensional spectrum. By analyzing this two-dimensional peak, resolution can be raised by leaps and bounds. MPGA needs not only the knowledge of energies of capture gamma rays, but also nuclear level structure data. While the energies are usually accurate, many of the excited level structures are poorly known. Complete sets of these nuclear data are of great importance. A new MPGA system will be constructed at the guide-hall of JRR-3M in Japan Atomic Energy Research Institute. This system consists of three clover Ge detectors with anti-Compton suppressors. The absolute efficiency of the system is about 10% for a 1.3-MeV gamma ray. It will be widely used in the fields of agriculture, engineering, geosciences, environmental science, and measurement of neutron capture cross sections of minor actinides.

This spectrometer consists of 30 Ge crystals and BGO anti-Compton shields. Generally, a data acquisition system for such a large Ge spectrometer consists of many NIM modules; it requires a large space and huge cost. To overcome these problems, we developed a new data acquisition system with digital signal processing techniques. This system is mounted in a 19-in. VME sub-rack, and the cost of this system is less than 2000 US dollars per one Ge detector channel.

    A compact 4pi Ge spectrometer was designed for the measurement of neutron capture cross sections of minor actinides. It consists of two EUROBALL clusters and four clover detectors with BGO shields surrounding a sample as close as possible so as to absorb a few gamma-rays of high energy emitted after the neutron capture reaction with reasonable efficiency. This feature opens up the possibility to discriminate the desired nuclide from other impurities based on the measurement of excitation energy and determine the cross section accurately.: Overall performances such as total detection efficiencies for 3 cascade gamma-rays as well as monochromatic gamma-rays were simulated using Geant4. It turned out we could achieve the peak detection efficiency as large as 0.9% for 3 cascade gamma-rays, which is almost an order of magnitude larger than the value of the Gammasphere.

    Nuclear magnetic resonance on oriented nuclei was carried out using a sample of dilute Y-91 and Y-91m in iron prepared by ion implantation of radioactive precursor Rb isotopes. For (YFe)-Y-91, the beta-ray asymmetry was utilized to measure the magnetic hyperfine interaction frequency, nu(0)=73.566(22) MHz, which led to the magnetic hyperfine field, B-HF=-29.4(2)T, by using the known nuclear g-factor. The field shift of the resonant frequency, dnu(0)/dB(0)=-2.501(17) MHz/T for (YFe)-Y-91, implies a Knight shift value, K=0.0(8)%. The interaction frequency and the field shift of (YFe)-Y-91m obtained via the gamma-ray detection confirmed the previously reported results. A ratio of the measured nu(0) and dnu(0)/dB(0) values for both (YFe)-Y-91 and (YFe)-Y-91m gave rise to the hyperfine anomaly, (91)Delta(91m)=-4.2(8)%, which can explain discrepancies in the B-HF values of YFe as determined by various experiments.

    We develop a 4 pi Ge spectrometer consisting of large-volume Ge detectors and BGO scintillators for capture cross section measurement of minor actinides such as Am-241,Am-243 and (237)Ap. By using this spectrometer we can extract summed gamma-ray energy, which corresponds to excitation energy of the residual nucleus after neutron capture reaction. The high energy resolution achieved by Ge crystals will enable us to distinguish between the nucleus of interest and impurity nucleus; we can eliminate the contribution from the impurity nucleus in the cross section measurements, enabling us to derive accurate cross section data In this paper we win describe detailed design study of the spectrometer and its performance based on the Monte-Carlo simulation code GEANT 4.5.0.

    To measure neutron cross-section data of the minor actinides, we construct a 4-pi Ge-spectrometer utilizing multiple gamma-ray detection method. This spectrometer consists of 30 Ge crystals and BGO anti-Compton shields. Generally, a data acquisition system for such a big Ge spectrometer consists of many NIM modules; it requires large space and huge cost. To overcome these problems, we developed a new data acquisition system with digital signal processing techniques. This system is mounted in a 19 inches VME sub-rack, and the cost of this system is greatly reduced.

    Nuclear magnetic resonance on oriented nuclei was used in combination with beta-ray detection and ion implantation, leading to the successful observation of the resonance of (SrFe)-Sr-91. The magnetic hyperfine field (B-HF) was deduced as B-HF(SrFe)=-23.83(7) T using the known nuclear g factor. This result explains the existing problem of disagreement in B-HF values for SrFe between theory and experiment. An experimental nuclear spin-lattice relaxation rate was obtained and is briefly discussed in comparison with a theoretical estimate.

    Nuclear magnetic resonance on oriented nuclei (NMR-ON) of La existing as a dilute impurity in Fe was observed for the first time. NMR-ON experiments were performed by detecting the 1596 keV gamma rays from the beta decay of La-140 in external magnetic fields of 0.1, 0.1 0.4 and 0.6 T. From the external magnetic-field dependence of the resonance frequency. the magnetic hyperfine field and the Knight shift were deduced to be B-hf = -47 +/- 1 T and K = -4.0 +/- 3.4% respectively. The effective relaxation time of (LaFe)-La-140 at 8 mK in an external magnetic field of 0.2 T was determined to be 8.8 +/- 1.5 min using a single-exponential fit. The present value of the magnetic hyperfine field agrees with that deduced from a two-site model by the low-temperature nuclear orientation method.

    The nuclear magnetic moment of the Ce-143 ground state (T-1/2 = 33.0 h, I-pi = 3/2(-)) has been measured with the technique of nuclear magnetic resonance on oriented nuclei (NMR-ON) at low temperature. A sample ((CeFe)-Ce-143) was prepared by implanting into an Fe foil nuclei of mass number 143, which were separated from fission products with an on-line isotope separator. The NMR-ON spectra were obtained by detecting specific beta and gamma rays, and the resonance frequency was thereby determined to be 84.3(1) MHz. Using the reported value of the hyperfine magnetic field at other Ce nuclei in Fe, the nuclear magnetic moment of the Ce-143 ground state was determined to be \mu\ = 0.43(1) mu(N). This value is discussed based on a systematics of the magnetic moments of other N = 85 nuclei.

    Brute-force nuclear magnetic resonance on oriented nuclei (BF-NMRON) experiments have been performed with 12 T maximum field and at 10 mK. The resonances for (TcNb)-Tc-95,96, (AgAg)-Ag-106-Ag-m, and 110Ag(m)Ag have been observed. The magnetic moment of Ag-106(m) was determined to be 3.705(4) mu (N). Comparing the resonance frequencies of BF-NMRON and those of the known NMR-ON results in Fe, the hyperfine anomalies in Fe were determined: (95)Delta (96)(Tc) = -0.026(17)%. (106m)Delta 110(m)(Ag) = 0. 10(6)%. The measured hyperfine anomalies are interpreted in terms of a microscopic theory including core polarization and exchange current effects.

The gamma-ray anisotropy measurements yielded values of the magnetic hyperfine field and the substitutional fractions of these ions in the host metals. An observed discrepancy between the substitutional fractions obtained from the 91 keV and 531 keV data on Nd-147 (Ni) under bar is briefly discussed.

    We have measured the polarization of unstable nuclei produced by the technique of ion beam surface interaction at grazing incidence (IBSIGI). A 60 keV Cs-124 beam from the on-line mass separator was used. The NMR technique was employed for the observation of the nuclear polarization. A small polarization of 0.22(13)% was observed. The small value was interpreted in terms of the velocity dependence of nuclear polarization, comparing with the results observed with stable nuclei.

    Boron Neutron Capture Therapy (BNCT) is a radiotherapy for the treatment of intractable cancer. In BNCT precise determination of B-10 concentration in whole blood samples is crucial for control of the neutron irradiation time. We firstly apply Charged Particle Activation Analysis (CPAA) utilizing a proton beam to non-destructive and accurate determination of B-10 concentration. Short-lived 511 keV annihilation gamma-rays have turned out to disturb the quick determination. By a simulation calculation based on the GEANT 4.10.2 code we have derived an optimal configuration of gamma-ray detectors to reduce the 511 keV gamma-rays. We constructed the detector system comprising a Ge detector and a BGO (Bi4Ge3O12) scintillator. We performed an experiment utilizing a proton beam, which proved the system effective in reducing the background by a factor of 1/29-1/41. The technique contributes to a quick determination of B-10 concentration in whole blood samples in the order of hours.

    The purpose of this study is to develop a small detection apparatus for proton computed tomography using silicon strip detectors and a calorimeter. We have improved the electronic circuits and FPGA program for the readout of SSD signals in order to enhance the speed of the system. The YAP (YAlO3(Ce) perovskite) , which is one of the fast inorganic scintillators, was also tested. It was confirmed that the energy resolution of YAP has enough performance at low-beam intensities and the SSD worked up to a beam intensity of 400 kHz. It was found there were more noises or pulse pileups than expected. They were caused by high-intensity beams.

    A phenomenon of large polarization of nuclei in a III-V semiconductor suddenly appearing below few K is theoretically predicted, under the condition that electrons of the semiconductor are optically excited from the valence band to the conduction band. The phenomenon is called DYNASP (DYnamic NucleAr Self Polarization). Theoretical and experimental study were carried out aiming at applying DYNASP to nuclear physics researches and the others. The effect of external magnetic field, in addition to the nuclear and the conduction electron polarization, was theoretically taken into an relationship on DYNASP. Appearance of large nuclear polarization of In nuclei in an InP semiconductor was successfully observed in an experimental study below 2.3 K. However, that was not concluded as a DYNASP phenomenon. It was found that further experimental and theoretical study is required.

    We invesitigated the change of the heart energy-getting system on the various heart conditions using the treated animals and heart-accumulated radiopharmaceuticals. In this study, we used three kinds of the treated animals described just below ; rats with chronic heart failure (CHF group), CHF group + heart-function improved agents (agent administration group) and mice with diabetes mellitus (DM group) and used the following three studies ; heart uptake study, fatty acid metabolic study, heart imaging study.
    In the study using CHF group, it has been shown that the heart energy-getting system with CHF is shifted from fatty acid use to sugar use. In the study using agent (PV) administration group, it has been shown that the heart-function recovery by PV is caused by the increase of the fatty acid metabolic function. In the study using DM group, it has been shown that with increasing damage by DM, the fatty acid uptake in the heart decreases, and the sugar uptake increases.

    A car-borne directional gamma-ray survey system was developed to contribute to effective decontamination of radioactive cesium. The system is composed of six CsI detectors surrounded by lead shields. The detectors are installed in six different directions: forward, backward, left, right, upward and downward. Therefore the system is used to measure gamma-ray incident from each direction.
    We showed that the developed system works as a car-borne directional survey system from measurement in the disaster zone.

    The purpose of this study is to develop a small detection apparatus for proton computed tomography. Silicon micro strip detectors (SSD) were used to obtain the proton track. Two sets of the X- and Y-strip detectors were each placed behind and ahead of the object. The residual proton energy was measured by the NaI(Tl) detector. We have measured the energy resolution of the NaI(Tl) detector and the 2D images of simple-shaped objects. It is found that the measurement of the upstream trajectory and the downstream independently is quite useful for spatial resolution of the object.

    Dynamic Nuclear Self Polarization(DYNASP) was theoretically predicted by Dyakonov et al. The phenomenon is observed in III-V semiconductors below a critical temperature(Tc). When electrons are excited to the conduction band with linearly polarized light, the lattice nuclei are largely self-polarized through the contact hyperfine interaction between the electrons and the lattice nuclei. The DYNASP theory was generalized by taking account of the conduction electrons polarized with circularly polarized light. To examine the DYNASP phenomenon below 4 K, an apparatus has been developed. The system is applicable to-NMR experiments for samples containing unstable nuclei, and pulsed NMR experiments for samples of stable nuclei.

    本年度は、昨年度に作成した検出器とPCを結ぶプロトタイプのインターフェース回路の不備を改良し、プリント基板におこし、多数枚のシリコン検出器に対応できるようにした。また、シリコン検出器のアセンブルも継続して行い、予定通り8枚のシリコン検出器を作成した。
    ベータ線源を用いたオフラインでのテストを行い、ベータ線を測定できることを確認した。また、アンプゲイン等のASICのパラメーターの設定を容易にするために、設定値を読み取るためのADコンバーターを付加した。
    完成した装置を国立がんセンター東病院の陽子線治療施設においてオンラインでのテストを行った。実験の実施においては、本装置のデータ収集の計数率が非常に低いため、ビーム強度を極限まで落として実験に望んだ。しかし残念ながら、陽子線を検出することは叶わなかった。オフラインでは動作する物がオンラインで動作しない原因として、多量に発生するであろうX線や加速器運転にともなう電磁ノイズがインターフェース回路を誤動作させているのではないかと考えている。その後、がんセンター東病院の陽子線施設は改修工事に入ったため、再実験を行う事はできなかった。
    装置の主要部は完成しているので、今後、X線や電磁波、電源ノイズ等の対策を行い、オンラインでの測定を成功させねばならないと考えている。

    To study the applicability of a new generation scintillation detector LaBr_3 for measurements of neutron capture cross sections for fast neutrons, its fundamental performances, such as energy resolution and response functions, were measured. Calorimeters composed of LaBr_3 scintillation detectors were designed and their performances were evaluated using the Monte Carlo simulation code, where their fundamental data on energy resolutions and response functions were used. The simulation showed that the LaBr_3 based calorimeter works as a powerful tool for the measurements of neutron capture cross sections.

    The beta-NMR measurements of the boron impurity in germanium were performed. The obtained results are as follows. Three resonances were found : a sharp resonance and a broad one around the Larmor frequency, a resonance at vqSplit=190 kHz. In the same manner as silicon, these three resonances were expected to correspond to the substitutional site (Bs), the site which shows polycrystal pattern (Bx), and the <111> axial symmetrical site (Bns), respectively. While the fraction of Bns is almost constant of 30 % below the temperature of 250 K, above 300 K the resonance disappears. This disappearance is also similar with the case of silicon, i.e., the spin-lattice relaxation should be caused by the fluctuation of the internal field due to the atomic jumps. The temperature dependence of the Bs+Bx was slightly different to the silicon case. Around the room temperature it decreases and makes a depression. One explanation for it may be that the chance for the interaction of Bs or Bx with the vacancy created by the implantation increases with the temperature, and it follows destruction of the polarization.
    In order to confirm the model of the atomic jump, the temperature dependence of the fractions of each site were measured under the different external magnetic fields. As a result, the temperature at which the NMR signal disappears agreed with the expected value by our model. This supports the validity of the atomic jump model.
    The nitrogen impurity in the compound semiconductor TiO2 and ZnO was also investigated. The electric field gradient at the nitrogen impurity in ZnO was measured. The nitrogen impurity in TiO2 locates at oxygen substitutional site and interstitial lattice site. While the substitutional nitrogen seems to be immobile, the defect around the substitutional nitrogen and the interstitial nitrogen seems to be mobile thermally.
