摘要：

Band mixing is used to reproduce the collective bands associated with shape coexistence in even-even osmium, platinum, mercury, and lead nuclei. The properties of the unperturbed bands are examined. The dependence of the unperturbed 2+ --> 0+ energies of the prolate intruder bands on N(pi)N(nu) is similar to that of the unperturbed normal bands if the intruder configurations are assumed to involve 4-proton, 4-hole excitations. The variation is reproducible using a restricted 2-component model of interacting proton and neutron shells.
