Outline of Final Research Achievements

In order to measure density distributions of unstable nuclei, we have constructed a new beam line at RIKEN Nishina center and installed our recoil proton spectrometer called ESPRI. As the 1st experiment we have succeeded to measure proton elastic scattering using the unstable 16C nuclear beam and the solid hydrogen target. For 12,13C we have measured elastic scattering of polarized protons at RCNP. For 14C we are now preparing radiation safety arrangements to avoid accidents. We have also successfully measured elastic scattering of protons from 90,92,94Zr at 200 MeV and 300 MeV to confirm to deduce proton and neutron density distributions independently and the data reduction and the analysis are in progress.
