Abstract:Detailed interpretation of data obtained from X-ray transmission measurements usually depends on the assumption that the contribution of each element is additive. This assumption yields the mixture rule for X-ray attenuation coefficients which is valid if molecular and chemical effects are negligible. We measured the total mass attenuation coefficients of V, Cr, Mn, Co and Ni in various their compounds. Absorption corrections were carried on data for ligands in the compounds. We found that V, Cr, Mn, Co and Ni have different total mass attenuation coefficients in the different compounds. We compared our results with theoretical values of Hubbell and Seltzer.
