21 Ne和21 Na的团簇结构

Cluster structure of 21Ne and 21Na

R. Bijker, F. Iachello

摘要:

在团簇壳模型(CSM)框架下研究了21 Ne和21 Na的团簇结构,发现它们具有复杂的团簇结构,同时存在20 Ne +n,20 Ne+p结构和19 Ne +2n,19 F+2 p结构.在~(21)Ne中识别出7个转动带,在~(21)Na中识别出4个转动带,分别对应于单粒子团簇态、单空穴团簇态和振动态。单粒子态与20 Ne +n和20 Ne +p团簇结构有关,而单空穴态与19 Ne +2n和19 F +2 p结构有关。

英文摘要:

We study the cluster structure of 21Ne and 21Na within the framework of the cluster shell model (CSM) and show that they have a complex cluster structure with the coexistence of a 20Ne+n, 20}Ne+p structure and a 19Ne+2n, 19}F+2p structure. Seven rotational bands are identified in 21Ne and four in 21Na and assigned to single-particle cluster states, single-hole cluster states and vibrational states. The single-particle states are associated with the 20Ne+n and 20Ne+p cluster structure, while the single-hole states are associated with the 19Ne+2n and 19F+2p structure.
