The study of energy bands in neutron-deficient 123,125Ce nuclei

Theoretical investigation of energy bands of 123,125Ce is performed by applying the projected shell model approach. The present calculation is viewed to reproduce the known experimental data of these nuclei, qualitatively. Not only this, the configurations of diverse bands are also obtained by an analysis of the band diagrams. The low-lying states of the bands are seen to arise from one quasiparticle configuration whereas the high-spin states arise from multi-quasiparticle configurations. The signature partner band of negative parity band is predicted in 123Ce. The ground state bands and relative energies of some bands with respect to them are predicted in 123,125Ce that can be helpful for future experiments.
