The percentage discrepancy between the derived mass attenuation coefficient and the tabulated FFAST values (circles) (Chantler, 2000BB10) over the energy range 8.5 keV to 11.59 keV, and the percentage discrepancies between XCOM tabulated values with Hartree–Slater calculations (crosses) (Berger & Hubbell, 1987BB4), Scofield tabulated values renormalized with Hartree–Fock calculations (stars) (Scofield, 1973BB65) and Rae et al. (2010BB52) measurements (squares). The near-edge region has a large discrepancy from current measurements due to the solid-state XAFS structure and the triangle effect. Renormalized Scofield (1973BB65) values deviate dramatically everywhere, implying that the earlier belief that correct theory lies between the unrenormalized and the renormalized predictions is not valid for these data.
