| 摘 要： | 本文彩和单电子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Ｃ４位形的最近邻的Ｆ－Ｈ对。对于ＳＴＥ光谱研究的理论配实验相符合。

| Abstract: | 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. |
