【摘要】 采用处理含有对力的推转壳模型(CSM)的粒子数守恒方法(PNC)研究了脱耦合项对正常形变奇A核171Yb的[521]1／2转动带的转动惯量随角频率变化的影响．在计算中同时考虑了单极对力和Y20四极对力,实验结果在PNC方法计算中得到了较好的重现．
【Abstract】 The effect on the variation of the moment of inertia in band 171Yb [521]1/2 is investigated using the particle number conserving (PNC) method for treating the cranked shell model with monopole and Y20 quadrupole pairing interactions. The experimental moments of inertia of 171Yb[521]1/2 (signature α=±1/2) and the blocking effect of proton are reproduced well by the PNC calculation, in which no free parameter is involved.
