A Survey of Nonrotational States of Deformed Odd-ANuclei (150<A<190)

Abstract

The configuration assignments for the known energy levels of the odd-$A$ deformed nuclei in the mass range $150<A<\mathrm{}190\mathrm{}$ have been systematically reviewed. For each nucleus, a summary is given of the intrinsic states that are considered well identified, and the main arguments that support particular assignments are outlined. A discussion is presented of the theoretical framework used in the analysis which is basically the Nilsson single-particle model with pairing correlations and Coriolis coupling taken into account, and with appropriate consideration given to vibrational excitations and their mixing with the one-quasiparticle states. Energy systematics are shown for the one-quasiparticle excitations and for the gamma-vibrational excitations (most of which have significant one-quasiparticle admixtures), and these systematics are discussed in terms of current theory.
