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

By using the phenomenological approach of Projected Shell Model (PSM), the positive and negative-parity band structures of odd mass neutron-rich 119–127 I 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 ( E 2 ) and B ( M 1 ) , are obtained from the PSM wavefunction for the first time for yrast bands of these isotopes.
