The study of neutron-decient nuclei in the A130 mass region has been an interesting subject in nuclear structure physics as this region is considered to be transitional region. In the present work, the positive parity rotational band structure of even-even 132,134Sm up to the high spin states has been studied in a microscopic frame work of calculations known as Projected Shell Model (PSM). Yrast spectra for 132,134Sm have been obtained from the PSM calculations and has been found to be in good agreement with the available experimental data. Besides this, the present calculations have also reported the occurrence of back bending at the same spins at which experimental data shows in both the nuclei.
INTRINSIC STRUCTURE AND HIGH SPIN POSITIVE PARITY STATES IN DOUBLY EVEN SE ISOTOPES

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.
