Study of nuclear structure for N=50 isotones at Z=28 shell closure

Abstract

The influence of filling the pfg proton shells on low-lying states structure for neutron-rich N=50 isotones have been studied for the nuclei ⁸⁰Zn, ⁸²Ge, ⁸⁴Se and ⁸⁶Kr. The shell model calculations have been performed in the model space jj45pn, using the effective interaction jj45pnb. Energies of low-lying states, reduced transition probabilities B(E2; J_i® J_f), the quadrupole moment Q and the deformation parameter are evaluated for studied nuclei, We compare the gotten results with available experimental data.
