Neutron and proton transition matrix elements and inelastic hadron scattering

The ratios of the neutron and proton transition matrix elements ( M n/ M p) have been studied for 0 + → 2 + transitions in single-closed-shell (SCS) nuclei by comparing inelastic hadron scattering and electromagnetic transition rates. The results show a general consistency from hadron scattering to...

Description
Summary:The ratios of the neutron and proton transition matrix elements ( M n/ M p) have been studied for 0 + → 2 + transitions in single-closed-shell (SCS) nuclei by comparing inelastic hadron scattering and electromagnetic transition rates. The results show a general consistency from hadron scattering to an accuracy ≈15% and show the systematic trend that M n/ M p > N/ Z (the collective-model result) for SCS neutron-valence nuclei and < N/ Z for SCS proton-valence nuclei, in agreement with schematic-model calculations of core-polarization effects.
