Abstract：
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.
