Abstract：
Based on a particle and a hole plus triaxial rotor model, treating the pairing correlations with BCS theory, we develop two quasiparticles plus triaxial rotor model to study the chiral bands. In this paper, fixing the proton as a pure h_11/2 particle, we investigate the influence of the neutron fermi surface on the excitation energies and electromagnetic transition probabilities of doublet bands.
