THE FINE STRUCTURE DEPENDENCE OF (np) 2 CONFIGURATION UPON THE COUPLING CASE

Using relative formula by calculating fine structure of double electron LS coupled and JJ coupled configuratons, the fine structure of (np) 2 component state under the circumstance of common couple was calculated. The change of the fine structure concerning types of couple was analyzed and the variation curvilinear of the fine structure energy level from LS couple to JJ couple was also obtained.
