Unified theory of particle-phonon coupling: Application to Sb and In isotopes using a realistic interaction

Abstract

A self-consistent, unified, microscopic theory ofparticle-phonon coupling is applied to the Sb and In isotopes, which are treated as proton-particle and proton-hole states respectively coupled to the ground and low-lying vibrational states of Sn. The particle-phonon coupling interaction is derived from the same realistic two-body interaction which gives rise to the vibrational excitations in Sn. Spectroscopic factors, level schemes and B( E2) values calculated with no adjustable parameters are shown to be in good agreement with experimental data.
