Scattering-matrix formulation of curved-wave multiple-scattering theory: Application to x-ray-absorption fine structure.
John J. Rehr,R. C. Albers +1 more
TL;DR: Curved-wave multiple-scattering contributions to XAFS (x-ray-absorption fine structure) are calculated with use of an efficient formalism similar to that based on the plane-wave approximation, but with scattering amplitudes replaced by distance-dependent scattering matrices.
