Standing wave enhanced scattering in multilayer structures

Abstract
X-ray standing waves inside a tungsten-carbon periodic multilayer structure are shown to act as localized probes in the coherent scattering from amorphous interatomic correlations making up the layers of the structure. The distorted wave approximation describes the standing wave formation, and kinematical theory describes the scattering of this standing wave by the amorphous atomic correlations. Possible use of this technique for the study of atomic arrangements and interfaces in multilayer structures is discussed.
