Proxy-SU(3)轨道对的壳模型结构

Shell model structure of proxy-SU(3) pairs of orbitals

Dennis Bonatsos, Hadi Sobhani, Hassan Hassanabadi

摘要:

在Proxy-SU(3)方案中,Nilsson轨道是每个壳层中具有最大总角动量的轨道,在壳层模型基中具有极其简单的结构|其中每个Nilsson轨道对应于单个壳模型本征向量。这个简单的结构在这些轨道的所有变形下都是有效的,而在其他轨道中,它只在小变形下有效。尼尔森0[110]对被发现对应于|1 1 1 0>对,为在壳模型内使用代理SU(3)近似铺平了道路。

英文摘要:

The Nilsson orbitals used in the substitutions occurring in the proxy-SU(3) scheme, which are the orbitals bearing the maximum value of total angular momentum in each shell, have an extremely simple structure in the shell model basis |N l j Omega>, with each Nilsson orbital corresponding to a single shell model eigenvector. This simple structure is valid at all deformations for these orbitals, while in other orbitals it is valid only at small deformations. Nilsson 0[110] pairs are found to correspond to |1 1 1 0> pairs in the spherical shell model basis, paving the way for using the proxy-SU(3) approximation within the shell model.
