Diffraction and scattering experiments at x-ray wavelengths close to an absorption edge has made it possible to distinguish even different valence states. Anomalous scattering factors derived from the XANES absorption data and the chemical shift show that the difference between f' (Fe2+) and f' (Fe3+) reaches up to 2.5. Here we demonstrate the possibility of va-lence-difference contrast methods.
