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

摘要: 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.Abstract: The SD-pair shell model was applied to study the even-even^94 Mo-^100 Mo.
