摘　　要：给出了Nilsson形变平均场加修正对力或邻近轨道对力模型的严格解及其近似角动量投影方法.作为进一步应用,给出了这两种模型对^(20)Ne低激发谱及约化电磁跃迁概率的计算结果并与实验进行了比较.An approximate angular momentum projection for the deformed Nilsson mean-field plus exactly solvable modified pairing model and the nearest-level pairing model is outlined,in which only intrinsic states with K=0 are taken in the projection.As a further application of the approach,lowlying level energies and some B（E2）values of ^20Ne are obtained from the projection of the two models,which are compared with the corresponding experimental data.
