Abstract
Among the many challenging problems concerning the structure of the closed shell , the question of the origin of the strength still predominates. We address this problem specifically, investigating within the context of the shell model the influence of excitations, core polarization, and meson exchange on transition rates. Although these mechanisms are usually responsible for quenching transitions, we present quantitative results indicating for the first time the possibility that transitions could be enhanced due to the above mechanisms.
