三角对称下d^（3，7）离子全组态EPR理论及其对激光晶体KZnF_3：Cr^（3＋）的应用

The EPR Theory of the Full-configuration State for d￣(3,7) ions in Trigonal Symmetry and Application to KZnF_3:Cr￣(3+)

本文借助于完全能量矩阵和Ｎｅｗｍａｎ的叠加模型建立了ｄ（３，７）（Ｃ）离子的全组态ＥＰＲ理论，并应用它研究了ＫＺｎＦ３：Ｃｒ（３＋）晶体．通过各向异性ｇ—因子及ＥＰＲ零场分裂参量Ｄ的研究，预言了Ｋ＋空位最邻近的Ｆ（－１）离子分别偏离Ｃ３轴２．６６１°和—１．１４９°．

The EPR theory of the full-configuration state for d(3,7) ions in trigonal symmetry,in terms of the full energy matrices and the Newman superposition,is established and applied to study the KZnF3:Cr(3+)crystals. The shift of the nearest neighbour F-ions of the K+ vacancy, 2. 661°and -1. 149°deviating from the C3 axis respectively,are prediced by analysing the anisotrop g-factor and the zero-field splitting of EPR.
