Microscopic calculation of inelastic proton scattering off O 18, Be 10, Be 12, and C 16 to study neutron excitation in neutron-rich nuclei MICROSCOPIC CALCULATION of INELASTIC PROTON ⋯ YOSHIKO KANADA-EN'YO and KAZUYUKI OGATA

Microscopic coupled-channel calculations of inelastic proton scattering are performed to study neutron excitations in the 21+ states of O18, Be10, Be12, and C16. The proton-nucleus potentials in the coupled-channel calculation are microscopically derived by folding the Melbourne g-matrix NN interaction with the matter and transition densities of the target nuclei obtained via structure model calculations of the antisymmetrized molecular dynamics. The calculated results reasonably reproduce the elastic and inelastic proton scattering cross section, and support the dominant contribution of neutrons in the 21+ excitation of Be12 and C16 as well as O18. The sensitivity of the inelastic scattering cross sections to the neutron transition density is discussed as well as the exotic behavior of the neutron transition density with amplitude in the outer regions of Be12 and C16.
