Rf^2组态谱项与光谱支项能量计算

CALCULATION OF THE ENERGY OF SPECTRAL TERMS AND SPECTRAL LEVELS IN F^2 CONFIGURATION

本文运用不可约张量法,对 f^2组态谱项与光谱支项及其相对能量进行了计算,从而确定了该组态各谱项以及光谱支项的能量高低顺序:~3H<~3F<~1G<~1D<~1I<~3P<~1S;

Using the irreducible tensor methods,this paper performs a calculation of spectral terms and spectral levels and its relative energy in f^2 configuration,from which we decide energy of spectral terms and spectral levels of this configuration in an ascending order as follows: ~3H<~3F<~1G<~1D<~1I<~3P<~1S; ~3H_4<~3H_5<~3H_6<~3F_2<~3F_3<~3F_4<~1G_4<~1D_2<~1I_6<~3P_0<~3P_1<~3P_2<~1S_0
