用处理推转壳模型的粒子数守恒方法分析了稀土奇A变形核173,175 Hf的3准粒子和 5准粒子高K转动带 ,包括转动惯量、顺排角动量 ,以及推转Nilsson能级上的粒子填布几率随转动角频率的变化 .计算中无自由参数 .实验观测结果在计算中得到较好地重现 .分析了多准粒子带与相邻偶偶核基态带的转动惯量变化规律不同的微观机制 .在这里Fermi面邻近高j闯入态的堵塞效应起了举足轻重的作用 The quasi-particle and quasi-particle high-K rotation bands of the rare earth odd-A deformed nuclei 173,175 Hf are analyzed by the method of conservation of the particle number of the shell model, including moment of inertia, tangent angular momentum, The probability of particle filling varies with the frequency of rotation angle, and there is no free parameter in the calculation.The experimental results are well reproduced in the calculation.The variation law of moment of inertia of multi-quasi- Micro-mechanism. Here, the blocking effect of Fermi near high j intrusion played a decisive role
