Theoretical investigations of the energy levels and EPR for CsBr∶Cr3+crystal

摘要：

　　In tetragonal ligand-field,the energy levels and third-order perturbation formulas of EPR (zero-field splitting D and g-factors) for 3d3/7 configuration ions have been constructed based on Zhaos Semi-SCF d-orbit wave functions model,Macfarlanes perturbation loop method and point-charge crystal field model.In these formulas,the contributions from configuration interaction,covalency effect,Racah-Trees corrections and local structure distortion have been considered.This theoretical system is applied to calculate the energy levels and EPR parameters of CsBr∶Cr3+ crystal at 293 and 77 K.The theoretical calculations are consistent with the experimental reports,and the results are discussed.
