摘　　要：The chiral doublet bands with three-quasiparticle configuration （πg9/2）-1 （vh11/2）2 are studied by the fully quantal triaxial particle rotor model. The energy spectra and B（M1）/B（E2） ratios of the doublet bands with different triaxiality parameter γ are systematically analyzed. It is found that γ is a sensitive parameter for the properties of these doublet bands.The chiral doublet bands with three-quasiparticle configuration （πg9/2）-1 （vh11/2）2 are studied by the fully quantal triaxial particle rotor model.
