摘要
本文根据Ｃｓ５Ｅｕ（Ｎ３）８的结构，用Ｍ．Ｒｅｉｄ的程序计算了它的晶场参数和强度参数，由此得出计算光谱图，同时通过能级拟合，对晶场能级进行了指认，并给出实验中的晶场参数．对它们的对称性进行了讨论．
The crystal field parameters and intensity parameters of the crystal Cs,Eu (N3)8 were calculated under the condition of the superposition model. Then using the energy levels given by Karl Gaiterer et al, the fitting program gave out the fitted crystal field parameters. When the fitting results came out, each energy level was assigned the irreducible representation.The symmetry on Cs5Eu (N3)8 crystal was discussed, the parameters of calculated and fitted were compared. Tile calCulated and experiment spectra were compared also.The enviroment around the rare earth ions Eu3+ in the mentioned crystal is actually C2 symmetry, the fitting results reveal this by comparing the correspondent parameters and the standard deviation of the fitting under different assumed symmetry.
