Study of nuclear structure of odd mass 119–127I nuclei in a phenomenological approach

Abstract

By using the phenomenological approach of Projected Shell Model (PSM), the positive and negative-parity band structures of odd mass neutron-rich 119–127I nuclei have been studied with the deformed single-particle states generated by the standard Nilsson potential. For these isotopes, the band structures have been analyzed in terms of quasi-particles configurations. The phenomenon of backbending in moment of inertia is also studied in the present work. Besides this, the reduced transition probabilities, i.e. B(E2) and B(M1), are obtained from the PSM wavefunction for the first time for yrast bands of these isotopes.
