Microscopic study of low-lying collectivebands in 77Kr

摘要

The structure of the collective bands in 77Kr is investigated within our deformed shell model (DSM) based on Hartree-Fock states. The different levels are classified into collective bands on the basis of their e??μ(e???2) values. The calculated e??? = 5/2+ ground band agrees reasonably well with the experiment. An attempt has been made to study the structure of the 3-quasiparticle band based on large e??? state in this nucleus. The calculated collective bands, the e??μ(e???2), and e??μ(e?‘€1) values are compared with available experimental data. The nature of alignments in the low-lying bands is also analyzed.
