Previous treatments have made the simplifying assumption that the effect of the EXAFS on the correction term is negligible, and that the samples are in the thick limit. We present a nearly exact treatment that can be applied for any sample thickness or concentration, and retains the EXAFS oscillations in the correction term.3 pages, 3 figure (eps), submitted to The 12th International Conference on X-Ray Absorption Fine Structure (XAFS XII)Condensed Mattertext
