AbstractAbstract
[en] The depolarization parameter Kyy' in the elastic scattering of 65 MeV polarized protons from deuterium has been measured using a newly designed spectrograph and a multi-foil polarimeter. Faddeev calculations using various nucleon-nucleon (N-N) interactions in a separable representation are compared with the data. The measured Kyy' values are well reproduced by a calculation using the N-N interaction with a tensor force which is adjusted to reproduce the empirical mixing parameter of the 3S1-3D1 partial waves. A rank-4 separable representation of the Paris potential by means of EST method (PEST) does not reproduce the data well. (author)

AbstractAbstract
[en] The continuous proton spectra from the deuteron break-up reaction on 4he have been studied at deuteron incident energies of 6.8 and 7.8 MeV with a magnetic spectrograph. The total reaction cross section was derived from the data at 7.8 MeV and compared with that calculated from the phase shift set obtained by the ETH group using the data from the elastic channel. Each spectrum has a peak corresponding to the formation of 5He ground state. The DWBA calculation carried out on the assumption that the ground state of 5He is described by a potential resonance, provides a good description of the angular distribution in the forward angles. In particular, the calculation using the Johnson approximation reproduces even the absolute magnitude of the cross section. (auth.)

AbstractAbstract
[en] A polarized ion source developed under the National Laboratory of High Energy Physics was transferred to the tandem accelerator in Kyoto University at beginning of 1993 to constitute a displacement of incidence into the accelerator. This was an atomic beam type polarized ion source, which is designed to adopt permanent magnets for 6 poles magnet to polarize the electron, to take out atomic nucleus on a shape of positive ion by ECR ionizer after transferring its polarization through transition using radio frequency (RFT), to make it negative ion by charge conversion using alkaline metal vapor, and to put it into the tandem accelerator. Test of the positive ion was finished at the National Laboratory of High Energy Physics, and test in Kyoto University was required after its negative ionization. As the estimated cost was unsufficient and entrance into the ion source facility in the tandem accelerator building was limited in Kyoto University, step of development was slow. Here is reported on present state of the ion source which is now operating stably. (G.K.)

AbstractAbstract
[en] We are developing Accelerator Mass Spectrometer (AMS) using 8 MV tandem accelerator of Faculty of Science, Kyoto University to measure long life heavy radio- isotope with high sensitivity. The multi target sputter ion source mounted 59 samples. A slit was installed in front of negative ion source to decrease beam emittance. The 3 μm aluminum foil was used to separate 13C4+ and 14N4+, 7Li2)4+ in the silicon semiconductor detector. Successive injection is realized by changing the magnetic field of injection section. The test sample was at first to become CO2. After purification, it was de oxidized by Hydrogen with Fe catalysis. The ratio of 14C/12C was obtained after estimation of the ion permeability efficiency. The tandem accelerator was not exclusive for the mass spectrometer. Therefore, we installed the second stripper (5 μm Mylar) between the 90 degrees analyzing magnet and the steering magnet to cancel out background signals. After all, this modification enabled to measure 14C by successive injection method. The reproducibility of data is less than 1 - 2 %, which is mainly due to the fluctuation of the electric current measurement. The chain operation time is about 2500 hours in a year. Meantime, the main trouble is a deterioration of cooling water quality. Exchanges of pipes and cleaning by chemicals were needed after the deterioration of water quality. Further optimization of detector system is being continued to increase sensitivity. (Y. Tanaka)

AbstractAbstract
[en] The differential cross sections for the 12C(d, p)13C reaction at a deuteron energy of 9.0 MeV have been measured with paying special attention to the transitions to the 5/2+ state at 6.864 MeV and the 3/2+ state at 7.677 MeV. The experimental results were compared with the second-order DWBA calculations that involve the inelastic excitation of 12C core using coupled channel form factors. The theoretical calculations reproduce the experimental data well. It has been shown that the two-step processes are dominant in the 12C(d, p)13C reaction leading to these states that have large fractions of the parentage of the excited state of target nucleus.
