摘　　要：通过模拟G.F.Chen小组和Heying小组测量的磁化率实验结果,得到了含铈稀土化合物CeRh2Ga和CeIrSi的晶场分裂能和相应波函数.计算结果表明,Kramers离子Ce3+六重基态2F5/2简并部分消除得到双基态;计算得到CeRh2Ga的第一激发能56 K与实验吻合较好.In this paper, we obtain the crystalline electric field（CEF） splitting levels and corresponding wave functions for CeRh2 Ga and CelrSi by means of simulating magnetic susceptibility measured by G. F. Chen and Heying group, respectively. The CEF analysis suggests that the six-fold ground state ^2 F5/2 of Kramers Ce^3 ＋ in CelrSi and CeRh2 Ga becomes a doublet ground state with the effluence of different symmetry electron field. The first excited energy 56K for CeRh2Ga is in good agreement with the experimental data.
