초록

A systematic study of nuclear structure properties of proton rich even-even positive parity 80,82,84Se isotopes have been studied within twobody self-consistent quantum mechanical framework known as Projected Shell Model (PSM)which incorporates quadrupole-quadrupole, monopole and quadrupole pairing interactions. The description of band structures of even-even 80,82,84Se nuclei based on the band diagrams indicates the presence of multiquasi-particle structure which provides us a unified understanding of ever accumulating high spin structure of these nuclei. The back-bending in moment of inertia, yrast spectra and g-factor have also been obtained and are also compared with the available experimental data.

Abstract

A systematic study of nuclear structure properties of proton rich even-even positive parity 80,82,84Se isotopes have been studied within twobody self-consistent quantum mechanical framework known as Projected Shell Model (PSM)which incorporates quadrupole-quadrupole, monopole and quadrupole pairing interactions. The description of band structures of even-even 80,82,84Se nuclei based on the band diagrams indicates the presence of multiquasi-particle structure which provides us a unified understanding of ever accumulating high spin structure of these nuclei. The back-bending in moment of inertia, yrast spectra and g-factor have also been obtained and are also compared with the available experimental data.
