EXPERIMENTALLY DETERMINED ANOMALOUS SCATTERING FACTORS FOR MN, FE, NI, CU, ZN AND HG USING THE KRAMERS-KRONIG RELATION

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 Fe0.716Ni0.242C0.042, Al0.963Cu0.015Zn0.022, Cd0.725Mn0.275Te and Hg0.80Cd0.20Te. 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.
