摘要
本文用等价算符法和不可约张量法,考虑~F_(7/2)与~2P_(5/2)的晶场相互作用,对Cs_2NaYbBr_6体系(O_h)中Yb^(3+)的实验能级进行了拟合计算,得到到晶场参数为B_(40)=1416 cm^(-1)、B_(60)=46cm^(-1),旋轨耦合参数ζ=2871 cm^(-1).同时,对计算结果进行了讨论.
It is showed in this paper that the energy level of Yb^(3+)in Cs_2NaYbBr_6 System(O_h)is calculated by equivalent opera-tor,the irreducible tensor method,and consideration of the crystal field interaction between ~2F_(7/2) and ~2F_(7/2).The crystalfield parameters,B_(40) and B_((?)0),are found to be 1416 cm^(-1) and 46 cm^(-1) respectively.The spin-orbit coupling parameter isfound to be 2871 cm^(-1),and at the same time the calculated results are discussed.
