| Abstract: | By using the crystal field theory, the author has calculated the energy levels of Cr 3+ vacancy center in MgO possessing C 4V symmetry and deduced the expressions for the g ‖=1.9824,g ⊥=1.9808 and D=-811×10 -4 cm -1 , the results are in agreement with the experiments (g ‖=1.9787±0.0006,g ⊥=1.9827±0.0006 and D=-819×10 -4 cm -1 ) |
