Abstract：
Using modified surface delta interaction,enlarging the gds configuration space to include the 1h_11/2 states with the negative-parity,the deformed Hartree-Fock calculations for the seven nuclei (¹⁰⁴Cd,¹⁰⁶Cd,¹⁰⁸Cd,¹¹⁰Cd,¹¹²Cd,¹¹⁴Cd and ¹¹⁶Cd) are performed. The ground-state and some particle-hole excited configurations are obtained. The calculated results show that there exist form transition and shape coexistence from mass number 104 to 116,and that the single-particle energy spectra are different not only for different mass number but also for different configurations of nuclei. At the same time,the approximate angular momentum projected Hartree-Fock(PDHF) method is applied to nuclei ¹⁰⁸Cd and ¹¹⁰Cd. And both of their positive- and negative-parity bands are obtained. The results of calculated energy spectra are consistent with experimental spectra well.
