Abstract

We investigate the properties of the excited spectra of the even-even isotopes of krypton using a Generalised Bohr Hamiltonian with three different Skyrme functionals. In particular, we investigate the evolution of the low-lying and states and their associated electromagnetic transitions. The model reproduces quite nicely the energy trends apart from 88Kr, where none of the interactions used here are able to grasp a sudden change in the energy spectrum. Additionally, we explore the neutron deficient region 72–76Kr which is a proposed region for shape coexistence. We observe that the model can reproduce the structure of the experimental spectrum of 72Kr exceedingly well.
