利用SD对壳模型讨论偶偶Mo核的集体性质(英文)

SD-pair Shell Model Calculation of Even-even Mo Isotopes

利用SD对壳模型讨论了偶偶Mo核低激发谱的集体性质。发现当SD对按照如下方法来确定,即对于两核子体系,通过对角化表面δ相互作用哈氏量,将SD对取为01+态和21+态,该模型可以合理的描述偶偶Mo核低激发态的集体性质。

The SD-pair shell model was applied to study the even-even^94 Mo-^100 Mo. It is found that with the SD pair determined as 01^＋ and 21^＋ states of a two-valence-nucleon system with a Hamiltonian, which contains the single particle energy term and the Surface-Delta interaction （SDI） between like nucleons, the collectivity of low-lying states can be described reasonably.
