Abstract

Abstract: We present, from a historical perspective, the evolution of instruments and techniques developed by our group, in conjunction with other collaborators, to establish a program in conversion electron spectroscopy that could be routinely implemented in radioactive decay studies. We focus here mainly on the investigations that bear upon the study of nuclear shape coexistence and its relation to electric monopole ( E 0) transitions. We show that many I π → I π ( I ≠ 0) transitions in both even and odd nuclei with mixed shape-coexisting configurations have large E 0 components accompanying their M 1 + E 2 strength (in some cases nearly pure E 0), and that this E 0 enhancement is a clear 'signature' for nuclear shape coexistence.
