Abstract

Properties of the ground state and first 2+ state of a large number of even-even nuclei in the Xe-Ba region have been calculated using a simple version of cranked Hartree-Fock-Bogoliubov model. The parameter set used has been obtained by fitting the ground state properties of some of the nuclei in this region. The sensitivity of the results to the choice of parameters has also been tested in a few cases. The shape rigidity of the nuclei in this mass region has been studied by generating energy contours in the β2-γ plane. Influence of the hexadecapole deformation on nuclei having flat energy surfaces in the γ direction has been examined. Higher angular momentum states also (up to 6+ or 10+) have been calculated in some of the nuclei to study the evolution of shape and nature of alignment with increasing spin.
