Abstract
A model of shape coexistence, based on an intruder {pi}(h{sub 9/2}){sup 2} excitation, previously applied to explain low-frequency upbending phenomena in {sup 171}Re and {sup 172}Os, is extended to heavier Os and Re isotopes. A phenomenological three-band mixing analysis of the yrast bands of even Os nuclei and the 5/2{sup +}[402] and 9/2{sup -}[514] bands of the neighbouring Re isotopes is used to deduce the excitation energies of the proposed intruder configuration as a function of neutron number. These are shown to be qualitatively consistent with an (h{sub 9/2}){sup 2} excitation. The implications of this model for other nuclei are discussed. 53 refs., 1 tab., 7 figs.
