Abstract
Shape coexistence effects on the structure and dynamics of the Z = N + 2 70Kr and N = 58 94Kr isotopes are explored in the framework of the complex excited Vampir beyond-mean-field model based on the effective interaction derived from a G-matrix starting from the charge-dependent Bonn CD potential and rather large model spaces. Results are presented on the evolution of shape-mixing and electromagnetic properties in the lowest two bands of both nuclei. Shape coexistence effects on the beta-decay properties of low-lying states in 70Kr are illustrated. The influence of shape mixing on the structure of parent and daughter states is realistically taken into account through independent chains of variational calculations.
