Nuclear Models, Particle Correlations, and Internal Conversion Coefficients

Abstract

This chapter reviews the place of internal conversion coefficient measurements in the current picture of nuclear structure to anticipate some of the future developments. The internal conversion coefficients (ICCs)—the ratio of the transition rates for electron compared to photon emission accompanying a change of state of an atomic nucleus—have been of great importance and interest in nuclear structure studies. No new systematic dynamic structure effects in internal conversion coefficients have shown up during the past five or so years of advance in the understanding of particle correlations in terms of new modes of motion. When the gamma transition takes place, but is hindered, the conversion coefficient sometimes differs from the value calculated from a static model. The deviation in the ICCs is smaller than in the gamma transitions.
