用曲柄壳模型研究了超流性对Cd-105和Cd-106反磁转动带的影响.实验的转动惯量和约化的B（E2）转变值被很好地再现。核超流性是再现实验转动惯量的必要条件。通过研究剪切角，即，揭示了双质子-空穴角动量的闭合及其对核超流性的敏感依赖性。
The effects of nuclear superfluidity on antimagnetic rotation bands in Cd-105 and Cd-106 are investigated by the cranked shell model with the pairing correlations and blocking effects treated by a particle-number-conserving method. The experimental moments of inertia and the reduced B(E2) transition values are excellently reproduced. Nuclear superfluidity is essential to reproduce the experimental moments of inertia. The two-shears-like mechanism for the antimagnetic rotation is investigated by examining the shears angle, i.e., the closing of the two-proton-hole angular momenta, and its sensitive dependence on nuclear superfluidity is revealed.
