- The aim of this paper is to present a comparison of the energy level schemes of $Cr^{3+}$ ($3d^{3}$ electrons) and $Co^{2+}$ ($3d^{7}$ electrons), each of ions doped, separately, in $MgF_{2}$ crystal. We report on the detailed and consistent crystal field analysis of $Cr^{3+}$ spectra in $MgF_{2}$ crystal and compare with results, previously obtained, for $Co^{2+}$, doped in same host matrix. The results are based on application of the exchange charge model of crystal field to the calculation of crystal field parameters and energy levels of both ions doped in $MgF_{2}$.The calculations have been performed on previously optimized geometry of $MgF_{2}$ crystal. The obtained results are compared with experimental data and discussed.
