摘　　要：本文采用单电子Hartree-Fork近似基础上的扩展离子方法研究MgF2 晶体中的自陷态激子(STE)的结构。研究表明这种晶体中的STE实际上是具有C1 位形的最近邻的F-H对。对于STE光谱研究的理论结果与实验相符合。The self-trapped excitons(STEs)in MgF2 are studied with the extended-ion method based on the one-electron Hartree-Fork approximation.It is found that the STE is in fact a nearest-neighbour F-H pair with C1 symmetry.The theoretial results for the spectra of the STEs are in agreement with the experimential data.
