The great power of NEXAFS derives from its elemental specificity and symmetry selection rules. Because the various elements have different core level energies, NEXAFS permits extraction of the signal from a surface monolayer or even a single buried layer in the presence of a huge background signal. We have calculated electron escape depth (lambda(e)) in Fe at the L-2,L-3 edge using pure Fe thin films of different thickness by soft x-ray absorption spectroscopy measurements. We have recorded high-resolution x-ray absorption spectra in transmission of Fe thin films resolving the near edge x-ray absorption fine structure. As a conclusion we found the mean escape depth of emitted electrons to be lambda(e) = 22 +/- 2 angstrom We believe our results provide important information for the improved understanding of theory of the photo absorption mechanism.
