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, 20Ne+p structure and a 19Ne+2n, 19F+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.

我们在簇壳模型(CSM)的框架内研究21 Ne和21 Na的簇结构,并表明它们具有复杂的簇结构,并具有20 Ne + n,20 Ne + p结构和19 Ne的共存关系+ 2n,19 F + 2p结构。在21 Ne中确定了七个旋转带,在21 Na中确定了四个旋转带,并将其分配给单粒子团状态,单孔团状态和振动状态。单粒子态与20 Ne + n和20 Ne + p团簇结构相关,而单空穴态与19 Ne + 2n和20 Ne + p团簇结构相关。19 F + 2p结构。
