HAMIL TONIAN MATRIX OF￣5D ION IN D_2 SYMMETRYAND ITS APPLICATIONS

本文推导了３ｄ~４／３ｄ~６离子~５Ｄ组态在Ｄ_２对称的晶体场中包括自旋－轨道、自旋－自旋和外磁场作用的哈密顿矩阵，并研究了ＺｎＳｅ：Ｃｒ^（２＋）中的零场分裂参量和塞曼谱。

In this paper.we derive the Hamiltonian matrix of￣5D(3d￣4 or 3d￣6)ion in D_2 symmetry, including the crystal field.spin-orbit.spin-spin and Zeeman interactions. Based on this matrix,the zero-field splitting parameters and the Zeeman spectra of ZnSe :Cr￣(2+)are studied.
