Experimental near‐ K ‐edge anomalous scattering factors f ′ and f ′′ for Fe, Ni, Cu, Zn and Mn as well as the L III ‐edge factors for Hg were determined from measured X‐ray absorption spectra using the Kramers–Kronig relation and the optical theorem in the alloys Fe 0.716 Ni 0.242 C 0.042 , Al 0.963 Cu 0.015 Zn 0.022 , Cd 0.725 Mn 0.275 Te and Hg 0.80 Cd 0.20 Te. While solid‐state effects modulate the scattering factors above the edge, the values provided by a modified FPRIME calculation match the experimentally determined values below the edge for all of the elements studied.
