讨论了单中子晕核11Be的能级翻转现象 ,指出晕核的单中子分离能Sn 与基态单中子的势阱内位置Dg 之间存在明显差别 .通过引进一种新的势阱———双MWS(ModifiedWoods Saxon)势 ,首次在平均场的层次上再现了11Be中 2s1 2 轨道与 1p1 2 轨道的翻转现象 ,而不再需要考虑当前普遍认为的组态混合解释 .由此认为 ,奇中子晕核中的能级次序翻转 ,反映了其平均场与稳定核的相比较存在着显著的差异 ,从而导致晕核体系反常壳结构的出现 .
The energy level inversion phenomenon of single neutron nucleus 11Be is discussed, and it is pointed out that there is a significant difference between the singlet neutron separation energy Sn of the nucleus and the position Dg of the potential well of the ground state single neutron. By introducing a new potential well- - Double MWS (ModifiedWoods Saxon) potential, the first time in the average field level reproduction 11Be 2s1 2 track and 1p1 2 orbit inversion phenomenon, and no longer need to consider the currently generally accepted configuration mixed explanation .Thus, The reversal of energy levels in odd halo nuclei reflects that there is a significant difference between their average field and stable nuclei, which leads to the appearance of anomalous shell structures of halo nuclei.
