摘要: The perturbation to the cubic crystalline field at rare-earth ions substituting cation in CaF2 is treated as a point-charge Coulomb of compensating ion. energy states and local charge compensation have enabled author calculate wavefunction g-values Yb3+ Ce3+ with tetragonal symmetry CaF2. results for turn out be reasonable agreement experimental g-values, while those seem not unsatisfactory.
