摘要Based on the triaxial particle-rotor model (PRM), the chiral doublet bands with symmetric particle-hole configurations pig(9/2) circle times nug, pih(11/2) circle times nuh and asymmetric configurations pig circle times nuh(11/2) , pih circle times nui(13/2) have been investigat ed, including their rotation spectra, the relations between spin and rotational frequency, and the reduced B (E2), B (M1) transition probabilities. These configurations correspond to regions A similar to 100, A similar to 130 and A similar to 170 in nuclear chart respectively. It is observed that the larger angular momentum provided by the valence nucleons, the higher the spin corresponding to the appearance of the chiral doublet bands, and the broader their spin interval. The chiral bands based on asymmetric configurations exhibit quite similar properties as those on symmetric ones, and can be discovered in future in-beam gamma experiments.
