摘要：

Based on the crystal- and ligand-field theory, the optical absorption spectra and electron paramagnetic resonance (EPR) g factor of Ni2+ ion at Mg2+ position in MgO have been investigated. The bond length (i.e. Ni2+-O2- distance) was determined from the cubic field parameter Dq: the crystal field Hamiltonian including the spin-orbital (SO) coupling effect of the ligand was diagonalized in the complete basis of 45 wave functions. Results of calculations are in a good agreement with experimental data. (C) 2010 Elsevier GmbH. All rights reserved.
