| 摘 要： | 本文通过引入两个共价因子Ｎ１、Ｎｅ推导了包含Ｒａｃａｈ参量Ａ的能量矩阵。并用高阶微扰方法推导了ｇ因子四阶微扰公式，在此基础上，计算了ＧａＡｓ：Ｃ２＋０的晶场光谱和顺磁ｇ因子。其理论值和实验结果吻合较好。本文结果表明，对于半导体，Ｒａｃａｈ参量Ａ对晶场光谱和ｇ因子的贡献不可忽略。

| Abstract: | Two covalent factors are introduced in this paper.Energy matrices of3d3/7,ion in Oh(Td)crgstal field and perturbation formulas up to fourth 2order for g factor,which include contribution from Racah Parameter A,are derived in terms of these fomulas,We calculate spectvnm and g factor of Co2+ in GaAs. The results agree with the experimental finding.For the semiconductor which has stronge covalency.It shows that the contribution from the Racah Paramater A to spectrum and g shifts can not be neglected. |
