Calculation of 4f^65d energy levels of Eu^(2+) ion in KX(X=Cl,Br,I) crystals

按着4f^6(~7F_J)和5dΓ_1耦合模型,提出了计算KX(X=Cl,Br,I)晶体中Eu^(2+)离子4f^65d能级的方法,导出了能级的参数表达式,并进行了数值计算,计算结果和实验符合较好.

According to the coupling model of 4f6(7FJ) and 5d , a calculating method for 4f65d energy levels of Eu2+ion in KX(X = Cl,Br, I) crystals was proposed. The parameter expressions of energy levels were obtained and the numerical calculations were carried out. The calculated results agree with the exprimental values.
