CaF_2晶体中四角对称的Yb^(3+)-F^-中心的电子顺磁共振参量的理论研究

Theoretical Studies of Electron Paramagnetic Resonance Parameters for the Tetragonal Yb^(3+)-F^- Center in CaF_2 Crystal

作者用考虑了二阶微扰贡献的理论公式和由光谱获得的晶场参量,计算了CaF2晶体中四角对称的Yb3+ F-中心的电子顺磁共振参量(g因子和超精细结构常数Ai),计算结果与实验结果符合较好.

The electron paramagnetic resonance(EPR) parameters for the tetragonal Yb^(3+)- F^- center in CaF_2 crystal have been studied from the second-order perturbation formulas and the parameters obtained from the optical spectra. The results are in agreement with the observed values.
