A systematic study of two-quasiparticle bands of the odd-odd 102Nb nucleus is performed using the projected shell model approach. Yrast band with some other bands have been obtained and back-bending in moment of inertia has also been calculated and compared with the available experimental. On comparing the available experimental data, it is found that the treatment with PSM provides a satisfactory explanation of the available data. [ABSTRACT FROM AUTHOR]

The characteristic nuclear structure properties of doubly odd 86Rb nucleus has been studied within two-body effective interactions incorporated in a self-consistent quantum mechanical approach known as - Projected Shell Model to test the efficacy of the chosen valence space. The Projected Shell Model (PSM) uses a truncated valence space under the assistance of the deformed mean-field solutions so as to make the calculations feasible. The influence of the high-j orbitals, h11/2 for neutrons and g9/2 for protons on the structure of 86Rb isotope is investigated in the present work by assuming an axial symmetry in the deformed basis. For this isotope, PSM calculations are performed to obtain the yrast line and also the description of the formation of the yrast level structure from multi-quasi-particle configurations. The back-bending in moment of inertia and transition energies have also been calculated and compared with the experimental data. The reduced transition probabilities, i.e., B(E2) and B(M1) for the yrast band are also obtained from the PSM wave functions for the first time, thereby extending an opportunity for the experimentalists to work for this data.
