Abstract

The β decay of the N=Z nucleus Kr72 has been studied with the total absorption spectroscopy technique at ISOLDE (CERN). A total B(GT)=0.79(4)gA2/4π has been found up to an excitation energy of 2.7 MeV. The B(GT) distribution obtained is compared with predictions from state-of-the-art theoretical calculations to learn about the ground state deformation of Kr72. Although a dominant oblate deformation is suggested by direct comparison with quasiparticle random phase approximation (QRPA) calculations, beyond-mean-field and shell-model calculations favor a large oblate-prolate mixing in the ground state
