Theory and applications of a semi-microscopic core-particle-coupling model

Pavlos Protopapas, University of Pennsylvania

Abstract

This thesis is devoted to the formulation and application of a semi-microscopic core-particle coupling model for the study of odd nuclei. It starts from the Kerman-Klein method, which contains as limiting form all known phenomenological models applied previously to this problem. We call attention to the versatility and power of the semi-microscopic modification of this method by Donau and Frauendorf, by adapting this method to several new applications as well as to improved treatments of some earlier applications. The physics of these applications is well-described by the conventional pairing plus quadrupole-quadrupole interaction with no ad hoc attenuation of the Coriolis interaction necessary. The only parameters fitted explicitly to the odd systems are the quadrupole coupling strength and the single-particle energies near the Fermi surface, which are allowed a modest adjustment compared to their Woods-Saxon values.
