Abstract
We investigate the dependence of the neutron-proton matrix element ratios (η) on radial neutron and proton ground state density distribution differences (Δ np) within the framework of the shell model quasiparticle random phase approximation. We show that theη ratios are linearly dependent onΔ nprms differences. We prove the consistency of empirical and theoretical methods by agreement of theη ratios obtained from the 1 GeV proton inelastic scattering analysis and from the QRPA calculations.
