Abstract：
Using modified surface delta interaction and enlarging the fp configuration space to include the 1g_9/2 states with the positive parity, the deformed Hartree Fock calculations for the six nuclei: ⁶⁴Ge,⁶⁶Ge,⁶⁸Ge,⁷⁰Se,⁷²Se and ⁷⁴Se are performed. The ground state and some particle-hole excited configurations are obtained. The approximate angular momentum projected Hartree Fock (PDHF) method is applied to nuclei ⁶⁴Ge and ⁷⁴Se. Both of their positive and negative parity bands are obtained. The calculated energy spectra are consistent with experimental spectra well.
