Abstract
A novel method based on the spherical wave formalism is presented to account the low-angle electron scattering processes in EXAFS. The usually used plane wave approximation is shown to be inappropriate when the electron forward scattering should be accounted. The developed formulae are used to obtain X-ray absorption spectra (XAS) of some crystals.
