The crystallographic problem: The Xray reflectivity spectrum exhibits a discontinuity like the X-ray absorption spectrum. However, the structures on these edges are not exactly the same because of the influence of the anomalous dispersion on the reflectivity. More specifically the white line (but also the edge within 100eV above) is enhanced. This precludes a comparison of the absorption spectra recorded by transmission and by reflectivity, so the comparison of the bulk and the surface is impossible.
