| Abstract: | The crystalline electric field(CEF) parameters,the CEF splitting levels and corresponding wave functions of compounds Ce3Rh2Ga2and Ce3Rh3Si2 are obtained by means of simulating the temperature dependence of inverse magnetic susceptibility measured by D.Kaczorowski group.The calculated results are in good agreement with the experimental data.The CEF analysis shows that Kramers ion Ce3+ has a doublet ground state. |
