原子核配对壳模型——侵入态与原子核形变

Intruder Level and Deformation in SD-pair Shell Model

摘要: 利用原子核配对壳模型讨论了侵入态对原子核形变的影响.计算结果表明,侵入态具有削弱原子核形变的趋势,对原子核的形变起着重要作用. The influence of intruder level on nuclear deformation is studied within the framework of the nucleon-pair shell model truncated to an SD-pair subspace. The results suggest that the intruder level has a tendency to reduce the deformation and plays an important role in determining the onset of rotational behavior.
