PrP5O14晶体中Pr3+离子的晶场参数和能级
Calculations of crystal field parameters and energy levels of Pr3+ ion in PrP5O14 crystals
摘要
本文在C_(2v)群近似下,以点群的不可约表示基矢为波函数,计算了PrP_5O_(14)晶体中Pr~(3+)的晶场参数,Racah参数,组态相互作用参数,自旋-轨道相互作用参数.计算中考虑了J混淆和J不混淆两种情况.计算了J混淆情况的能级,并指派了不可约表示,计算和实验能级符合较好.
Abstract
By using basic vector of point group irreducible representation as the wave function, the crystal field parameters, Racah parameters, spin-orbit interaction parameter and configuration parameters of Pr3+ ion in PrP5O14 crystals are calculated in this paper. Both J mixing and no-J mixing cases are considered. The energy levels of J mixing case are given and assigned for corresponding irreducible representations. The calculated result is in agreement with experiment.
