Consistent interpretation ofB(E2) values andgfactors in deformed nuclei

Abstract

A simple phenomenological model is discussed that simultaneously accounts for the saturation of B(E2; ${0}_{1}^{+}\ensuremath{\rightarrow}$ ${2}_{1}^{+}$) values and the newly recognized near constancy of g(${2}_{1}^{+}$) factor values in deformed nuclei. The model invokes reduced effective contributions to these observables from the valence neutrons and protons. Empirical evidence supporting this ansatz comes from recently extracted proton-neutron interaction strengths.
