采用考虑轴向形变的相对论平均场理论 ,以双中子、双质子分离能隙δ2n δ2p作为壳封闭的特征 ,分析了Mg ,Si和S同位素链的壳封闭和壳反常 ,发现Mg同位素链在N =12 ,16处 ,Si同位素链在N =14 ,S同位素链在N =16处出现明显的壳封闭结构 ,Si同位素链在N =2 8处壳层结构并没有消失 .Mg ,Si和S同位素链在N =2 0处壳效应并不太明显
Based on the theory of relativistic mean field considering the axial deformation, the shell closure and shell anomalies of the Mg, Si and S isotope chains were analyzed by using the energy gap δ2n δ2p, At N = 12 and 16, the Si isotope chain is N = 14, and the S isotope chain has obvious shell-closed structure at N = 16. The shell structure of Si isotope chain at N = 28 does not disappear. The S isotope chain at N = 20 shell effect is not obvious
