Abstract
Some N=80 isotones (144Gd, 146Dy and 148Er) have been studied by using the HFB framework and the nuclear structure properties like yrast spectra, subshell occupation numbers and quadrupole moments have been obtained. Intrinsic quadrupole moments obtained from HFB calculations show a gradual increase as one moves from 144Gd to 148Er indicating, thereby, an increase in deformation, which is in agreement with the experimental results. From the results of subshell occupation numbers, it is clear that subshells 3s1/2, 2d3/2, 2d5/2, 1g7/2 and 1h11/2 of protons are contributing towards the development of deformation as one moves from 144Gd to 148Er.
