Abstract.

Deformed configuration mixing shell model based on Hartree-Fock states with extension to include isospin projection (DSMT) for two- and four-particle configurations (generated by particle-hole excitations) is applied to study the structure of the low-lying T = 0, 1 and 2 bands (or levels) in the even-even N = Z nuclei 52Fe and 72Kr. The pf-shell KB3 interaction for 52Fe and a modified Kuo’s interaction for 72Kr are employed in the calculations. In this first application of DSMT with four-particle T projection, low-spin (J ⩽ 10) members of the T = 0, 1 and 2 bands in 52Fe are compared with experiment including the known E2 transition strengths. The agreement between DSMT and experiment is reasonably good. Similarly, the low-spin members of the observed (prolate) yrast band in 72Kr are also well described by DSMT.
