Reflection-mode EXAFS spectra of a steel sample covered with a native oxide layer at different absorption edges: (a) Fe K-edge for incidence angles φ = 0.1° and φ = 0.25°. In the inset the k2-weighted reflectivity fine structures ΔR(k)k2 are shown. (b) Cr K-edge for an incidence angle φ = 0.25°. The arrow marks the position of the Mn K-edge, which is displayed in the inset for φ = 0.1°. |
