摘要
The complete strong--field--matrices for d^(2,8)(C_(3v)~*) ions are constructed within an O_h-point--group representation. Based on the eigenvalues and eigenvectors of these matrices, acomplete-configuration--mixing EPR theory is established for Ni^(2+) ions in CsMgX (X=Cl,Br,I) kind crystals, and accordingly, a uniform calculation is performed for the opticalabsorption spectrum, the zero-field--splitting and Zeeman splitting of the ground state, theEPR parameters D and g and the EPR conditions (B,hv) of Ni^(2+) impurity ions in a CsMgCl_3crystal. The results are in very good agreement with the experimental, thus a uniform theo-retical interpretation is achieved for the optical and magnetic properties of Ni^(2+):CsMgCl_3for the first time.
