Abstract: A I l l 1 3 V d .a The refractive indices of many crystals are well known in those spectral regions where the materials are transparent.On the other hand, very few data exist on either the refractive index, n, or the absorption index, k, for these materials beyond their ultraviolet transmission limits.spectrum of crystalline magnesium oxide included the intermediate derivation of the optical properties as far as 28 eV.Part of our research program on the electronic The experimental procedure consisted of the measurement of the near-normal-incidence reflectance spectrum of freshly cleaved crystals of magnesium oxide from 4 to 28 eV.If the-ratio of the ' reflected and incident light intensities is denoted by r , then it , 2 is possible to derive the following relationships, via the Fresnel equations: 2
