Abstract

The properties of low-lying states in 76Ge, especially the characteristics of the mixed-symmetry states, have been investigated within the neutron-proton interacting boson model (IBM-2). By considering the relative energy of d proton boson to be different from that of neutron boson, the low-lying positive parity levels and M1, E2 transition strengths have been calculated. The IBM-2 calculated results are in good agreement with the experimental data. Particularly, the mixed-symmetry states have been reproduced quite well. The calculation and systematic analysis demonstrated that the collective character of 76Ge lies closest to the SU*πv(3), with some possible Oπv(6) dynamic symmetry in IBM-2 viewpoint.

Keywords
