摘要
本文采用晶场理论，计算了ＭｇＯ中Ｃｒ３＋空位中心Ｃ４ｖ、对称四角畸变的能级和ＥＰＲ（电子顺磁共振）参量ｇ＝１．９８２４，ｇ⊥＝１．９８０８和Ｄ＝－８１１×１０－４ｃｍ－１，得到了与实验（ｇ＝１．９７８７±０．０００６，ｇ⊥＝１．９８２７±０．０００６和Ｄ＝－８１９×１０－４ｃｍ－１）一致的结果，解释了ｇ因子各向异性的起因．
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 )
