We did a similar procedure (extracting back scattering properties from
reference samples), although with FEFFIT, which is the predecessor of
IFEFFIT. It should be also done by IFEFFIT by back Fourier transforming the
reference samples and extracting amplitude and phases - they can then be
combined in the "corrected" EXAFS equation which can be fit to the data by
Artemis - with modified amplitude and phase factors. Here is the reference:
