本文利用粒子转子模型研究转动惯量对 A~60区原子核手征转动的影响。根据先前的研究，所采用的粒子-空穴组态为 πf7/2-1?νg9/21，形变参数 β=0.25，γ=34°。论文将采取包含常转动惯量与可变转动惯量的粒子转子模型（分别为PRM+CMI与PRM+VMI）研究对应的能量最低的6条转动能带能谱，电磁跃迁性质，角动量分布和 K 分布等。结果表明，对于β=0.25，γ=34°的原子核，除了Band1与Band2外，在PRM+CMI与PRM+VMI的计算中，预测的Band3与Band4也可以解释为手征双重带。

In this paper, particle rotor model is used to study the effect of moment of inertia on nuclear chiral rotation in A~60 region. According to previous studies, the particle-hole configuration is πf7/2-1?νg9/21 with deformation parameter β=0.25 and γ=34°. In this paper, a particle rotor model with constant and variable moments of inertia is adopted to study the energy spectrum of six rotational bands with the lowest energy, electromagnetic transition properties, angular momentum distribution and K distribution. It is shown that, besides Band1 and Band2, the predicted Band3 and Band4 in the calculations with both PRM+CMI and PRM+VMI for atomic nuclei with β=0.25，γ=34° can also be interpreted as chiral doublet bands.
