在80~300K的不同温度范围内，测量了LiF和MgF_2的折射率，从200 nm到它们各自的截止波长，其折射率的测量精度均优于±0.003。数据用两项色散方程进行拟合。激子峰对应的振子强度值(LiF和MgF_2分别为0.45和0.69)与已有数据一致。
The refractive indices of LiF and MgF2 have been measured with an accuracy better than ±0.003 from 200 nm down to their respective cutoff wavelengths for various temperatures ranging from 80 to 300 K. For LiF, the temperature coefficient changes sign at 160 nm. The data were fitted to a two-term dispersion equation. The corresponding oscillator strength values for the exciton peak (0.45 and 0.69 for LiF and MgF2, respectively) are in agreement with existing data.
