Abstract
The Kr isotopes with A=72 to 84 are investigated within the interacting boson model (IBM-2) using two different approaches. In the first investigation the single-particle energies of the neutron and proton bosons are assumed equal, ε==, whereas the second investigation is based on their being different (≠). The results of these calculations are compared with the experimental data and previous theoretical investigations. We also attempt to determine the shape transition in these nuclei.
