摘　　要：将奇核轴对称转子加准粒子模型推广到奇奇核的情况，考虑了在奇奇核的基矢空间中计及模型的质子—中子相互作用项，方法用于Ａ＝１６０号区多个实际核的计算，所得结果均与实验值定性相符．文中还对奇奇核Ｓｉｇｎａｔｕｒｅ反转的一种可能的机制进行了讨论．The well known axial rotor plus quasiparticle model for odd nuclei is generalized to odd-odd nuclei.The proton-neutron interactions are considered in the base-space of the model for the first time.The method presented in this paper is used for several realistic nuclei in A=160 area.The results agree with experimental data qualitatively.A possible mechanism for Signature inversion of odd-odd nuclei is also discussed.
