| Abstract: | The complete strong-field matrices have been established for d~8 ions in C_3(?)* symmetry,onsidering the spin-orbit
interaction,within the O(?) point group representatives.Consequently,the optical absorption spectrum,the zero-field split-
ting parameter D,the paramagnetic g-factors and the Zeeman energy of the CsMgCl_3:Ni~(2+)crystals have been calculated
theoretically.The results are consistent with the experimental values.Thus the physics of the optical and the paramagnetic
properties are well understood.Also,the effect of the excited states on the ground-state properties has been discussed. |
