Identify Four 8~+ States in ~(80)Kr Nucleus Within Microscopic Approach

Using microscopic sdIBM-2+2q.p. approach, the level s of the groundband, γband and twoquasiparticle band for 80Kr n ucleus are calculated. The data obtained show agreement with the recent experime ntal results. The model identifies that the 8+1 state, 8+2 state, and 8 +3 state maybe belong to the ground state band, quasineutron and quasipr oton band, respectively, while the 8+4 state is a member of γband. The th eoretical calculations indicate that no the distinct change of nuclear state is caused by the abrupt broken pair of a boson. The problem of the energy and the i dentification of twoquasiparticle band are discussed yet.
