Nuclear Structure Study of 62Ni, 62Zn and 62Cu Nuclei by using SDI and MSDI Interactions

The nuclear shell model calculations are employed to nuclear structure study of the nuclei 62Ni, 62Zn and 62Cu in fpg9/2 model space. The inert core 60Ni is assumed, with two nucleons outside inert core are considered to describe the binding energy and excited states for both the positive and negative parities of the three nuclei. A computer code were written by Mathematica to perform the configuration mixing and pure shell model calculations by taking the surface delta interaction (SDI) and modified surface delta interaction (MSDI) as residual interactions. The binding energy calculations were in excellent agreement with experimental data. The predicated ground-state and low-lying states (energies, spins and parities) for the 62Ni, 62Zn and 62Cu are compared with the recent available experimental data. A reasonable agreement were obtained by comparing our theoretical work with the experimental data.
