Multifaceted impact of shape coexistence and mixing on 96Y to 96Zr and 92Rb to 92Sr allowed and first-forbidden β− decay was investigated within the beyond-mean-field complex Excited Vampir variational model. The structure of the parent and daughter states and the β-decay properties have been studied using the effective interaction obtained from the G matrix derived from the charge-dependent Bonn CD potential and a large model space. Various effects of shape coexistence and mixing on the properties of the involved states and comparison to the available experimental data will be presented.
Petrovici et al. (Fri,) studied this question.
