1. Microscopic Study of Band Structure of 102Nb.

Author

Singh, Suram, Kumar, Amit, Gupta, Surbhi, Gupta, Anuradha, Singh, Dhanvir, and Bharti, Arun

Subjects
*QUASIPARTICLES, *NIOBIUM, *NUCLEAR shell theory, *YRAST states, *INERTIA (Mechanics)
Abstract

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]

3. Theoretical study of neutron-rich 107,109,111,113Rh isotopes.

Abstract

A theoretical study of the structure of some odd mass Rh nuclei in the A ~ 100 mass region is carried out by using the angular momentum projection technique implemented in the projected shell model (PSM). The influence of the high-j orbitals (h11/2 for neutrons and g9/2 for protons) on the structure of 107-113Rh isotopes is investigated in the present case by assuming an axial symmetry in the deformed basis. For these isotopes, the structure of multi-quasi-particle qp bands is studied along the yrast line in detail. Further, the phenomenon of back-bending is also studied theoretically and is found to be in agreement 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 providing an opportunity for the experimentalists to work for this data.
