| Abstract: | In this paper,by considering the difference between the t 2g and e g orbits of the d electrons,and the contribution of Racah param eter A to spectra transition as well,we derive the Hamilton matrix o f 3d-7 ion in T d symmetry.Based on this matrix,the optical absorption spectra of Co- 2+ doped MgGa 2Se 4 is studied.The results agree with the experime ntal data very well. |
