介绍Nilsson形变平均场加修正对力模型的严格解并介绍模型的角动量投影方法,其中仅考虑了K=0的内禀态.作为该模型方法应用的简单例子,给出了模型对18O和20Ne的低激发谱及其约化电磁跃迁几率的计算结果.
The angular momentum projection for the deformed Nilsson mean-field plus an exactly solvable modified pairing model is outlined,in which only intrinsic states with K=0are taken in the projection.As simple examples,low-lying level energies and some B(E2)values of ^18O and ^20Ne are obtained from the projection.
