| Outline of Final Research Achievements |
Elastic scattering of Sn132 beam from a large and thin (32φ and 1mm in thickness) solid hydrogen target was measured successfully at 200A ( A: mass number of the beam) MeV at RIBF. Data reduction and the analysis are now in progress. We plan to deduce proton and neutron density distributions simultaneously by analyzing both of the 200A and the next 300A measurements. In order to confirm the correctness of our method, we measured proton elastic scattering at RCNP from Zr90 at Ep=200 MeV and 300 MeV and tried to deduce both proton and neutron density distributions. The deduced proton density distribution of Zr90 was found to be consistent with the one obtained from the charge distribution by the electron scattering experiment. We have developed a new Xe-gas scintillator for the next 300A MeV Sn132 beam measurement and are waiting for the beam time at RIKEN.
