类铍Ar^（14＋）和类镁Ar^（6＋）离子双激发态能级的计算

CALCULATIONS OF ENERGIES OF DOUBLY EXCITED STATES OF BERYLLIUM-LIKE ION Ar￣(14+) AND MAGNESIUM-LIKE ION Ar￣(6+)

用组态相互作用方法计算了类铍Ａｒ１４＋离子双激发态１ｓ２３ｌ３ｌ＇和类镁Ａｒ６＋离子双激发态１ｓ２２ｓ２２ｐ６４ｌ４ｌ＇的能级。两个外层电子与内层原子实１ｓ２或１ｓ２２ｓ２２ｓ６电子的作用用模型势表示。Ａｒ１４＋的双激发态可用量子数Ｋ，Ｔ和Ａ标记，而Ａｒ６＋的某些组态却不能用上述量子数表示。

Energy levels of 1s2 3131' doubly excited states of beryllium-like ion Ar14+ and 1s22s22p64l4l' doubly excited states of magnesium -like ion Ar6+ are calculated using the configuration interaction method. The interactions of the two outer electrons with the inert 1s2 of 1s22s22p6 core electrons are represented by a model potential. All doubly excited states o f Ar14+ can be designated by quantum numbers K, Tand A, but some of these states of Ar6+ can not be designated by these quantum numbers.
