Empirical calculations for ground state band level energies of 76Kr and 74Se nuclei

The neutron deficient nuclei 76Kr and 74Se (N=40) in the mass region A=80 exhibit interesting properties like shape coexistence, triaxiality, large quadrupole deformation patterns, strong upbends in kinetic moment of inertia of yrast bands and complex band structure. The spectroscopy of these nuclei is of special interest because both the proton and neutron shells are partially filled which results in large deformation in the ground state
