摘要：

The structure of the collective bands in Kr-77 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 B(E2) values. The calculated K = 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 J state in this nucleus. The calculated collective bands, the B(E2), and B(M1) values axe compared with available experimental data. The nature of alignments in the low-lying bands is also analyzed.
