Measurement of deep hole states in $^{40}$Ca by 392 MeV (p,2p) reaction

ORAL

Abstract

We performed $^{40}$Ca($p,2p$) experiment with 392\,MeV polarized proton beam at RCNP Osaka University and measured recoil momentum distribution of cross section and analyzing power for low lying and deep hole states in $^{40}$Ca. The aim of this experiment is to obtain information on the spectroscopic factor and the width of the deep orbital states such as the $1s_{1/2}$ state of medium nuclei for understanding the nuclear structure and correlations in deep hole states. We analyzed deep hole states with L decomposition analysis method which disentangle the contributions of each orbital states from separation energy spectra.We will report the result of $^{40}$Ca measurements.
