Paper Abstract

A reliable estimate of the properties of isomers that may be viable candidates for a gamma-ray laser requires the use of the most accurate wave functions possible. The majority of models that have been used to estimate the properties of isomers are applicable to only selected regions of the nuclear mass table. In particular, the Bohr-Mottelson model of odd-A and odd-odd nuclei will fail if the even-even core is not strongly deformed or if the deformations are changing strongly as a function of mass. The problem is overcome in a new core-quasiparticle model for odd-odd nuclei; it is a generalization of work by Donau and Frauendorf-'2 for odd-A nuclei. The model introduces the pairing interaction ab initio; the odd-A states are mixtures of particle and hole states. The core may be soft towards deformation or axial asymmetry and may change rapidly as a function of mass. Thus, the model is ideally suited for application to the region of transitional nuclei such as the Te, La, and Os regions.
