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-richN=50 isotones have been studied for the nuclei 80Zn, 82Ge,84Se and 86Kr. The shell model calculations have beenperformed in the model space jj45pn, using the effective interaction jj45pnb.Energies of low-lying states, reduced transition probabilities B(E2; Ji® Jf), the quadrupolemoment Q and the deformation parameter are evaluated for studied nuclei, Wecompare the gotten results with available experimental data.
