X-Ray Absorption Near Edge Structure (XANES) Studied by the Short-Range Order Multiple Scattering Theory

Abstract

We propose the short-range order multiple scattering XANES theory based on the method previously developed by us. In this method, atoms are not classified into shells but the scattered waves are classified into a direct term and a fully multiple scattering term. This classification is useful to derive the XANES formula which can directly be compared with EXAFS formula. This method can be easily applied to considerably large systems. We show how the structural information is obtained from the XANES spectra.
