Multiple Scattering Effects in EXAFS (Extended X-Ray Absorption Fine Structure): Comparison between Theory and Experiment for Pt Metal.

Abstract

Extended x-ray absorption fine structure (EXAFS) model functions have been calculated for the LIII edge in Pt metal. All single, double and triple scattering contributions were taken into account, using a recently developed multiple scattering formalism. Theoretical values for the scattering amplitude, phase, and Debye-Waller factor and the 'universal curve' for the electron mean free path have been used. Comparison to experimental data gives an estimate of the limitations in the current formalism, and shows that multiple scattering effects are important in Pt only at radial distances corresponding to fourth shell nearest neighbors.
