| 摘 要： | 采用含有对力的推转壳模型(CSM)的粒子数守恒方法(PNC)研究正常形变奇A核^171Yb的521]1／2带的单粒子轨道对转动惯量的贡献．同时考虑单极对力与四极对力，实验结果在PNC方法的计算中得到了较好的重现，特别是来自每一个大壳和每一个推转的Nilsson轨道的贡献的微观机制也得到了很好的展现。

| Abstract: | The investigation into the K=1/2 rotational band has not attracted much attention because of the decoupling term which changes the I (I+1) rule of the energy chart. This paper displays the expressions of the rotational spectra in the K=1/2 rotational band and investigates into the variation in moments of inertia with rotational frequency for normally deformed band 171Yb521]1/2 in rareearth oddA nuclei by using the particlenumber conserving(PNC) method for treating pairing interaction(monopole and quadruple).The observed variations of J are reproduced well in the PNC calculation, particularly the microscopic mechanism(contribution from each major shell and each cranked Nilsson orbit)is clearly displayed. |
