主　　题：Radiation damage Rare earth Doped BaF₂ crystal 

摘      要：The Discrete variation Xα（DV-Xα）method was used to calculate the energylevel of some rare earth doped BaF2 *** results indicated that elements Eu,Dyand Yb will change their valence from +3 to +2 under irradiation and thus change theoptical properties of the *** calculation using radiation damage model agreeswell with experiments.
