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.
