摘　　要：本文采用一种适用于共价晶体的含双共价因子 (Nt≠ Ne)的能量矩阵计算方法 ,研究了 Co2 +离子在 Hg S中的光学吸收谱 ,并对结果进行了讨论 .研究结果表明 ,对于共价性强的晶体 ,Racah参量In this paper,we have studied the optical absorption spectra of Co 2+ doped covalent crystals HgS by using a method in which the double covalency factors N t and N e are introduced in the energy matrices,then the calculated results are discussed.We find that the contribution of Racah parameter A to spectra transition may not be neglected in the more covalent crystals.
