Description
Study of nuclei with exotic neutron to proton number ratios is one of the frontiers in the quantum many-body system of nucleons. To clarify the size and structure of neutron-rich and neutron-deficient nuclei, we have applied proton elastic scattering as a different probe from electron scattering. It is essential to determine the proton and neutron density distribution of neutron-rich and neutron-deficient nuclei, which is related to symmetry energy in the equation of state (EoS) of nuclear matter. Measurement of proton elastic scattering for 50Ca, which is a neutron-rich nucleus, has been performed at RIKEN RI Beam Factory (RIBF). In this study, a new experimental setup with Silicon Strip Detector (SSD) has been adopted for detection of recoil protons. In this presentation, results of the developmental measurement of proton elastic scattering will be reported and distribution of excited energy, that demonstrates how well elastic and inelastic scattering events can be separated, will be discussed.
