摘要
Near surface layers structure data as r, N, sigma, Delta E(0), and known phases and amplitudes as well as thickness were used for the evaluation of X-ray reflection spectra. With these data, the energy dependent index of refraction n = 1 - delta - i beta for each layer can be calculated. The application of the Fresnel theory to an assumed layer structure yields the reflectivity as a function of the energy. As an example, oxidized copper surface is discussed.
