Abstract
We have performed a spherical wave analysis of the EXAFS spectra of hydrogenated amorphous silicon in order to detect contributions due to the next nearest neighbor scattering and/or multiple scattering. A high frequency oscillation was found that could be interpreted in terms of a second-shell contribution without multiple scattering effects. A feature which could not be explained in the one-electron scheme was identified and tentatively attributed to a many-electron effect.
