Band Interaction between Chiral Doublet Bands

Band interaction between the chiral doublet bands based on πh_11/2⊗νh⁻¹_11/2 configuration is investigated in the particle rotor model with different triaxial deformation γ. The variation of chiral partner states with γ values is understood qualitatively based on the basic picture of two interaction levels, which is confirmed further by the calculated overlap integral of wave functions at different γ values. It is found that the interaction strengths of chiral partner states are obviously different for odd spins and even ones.
