Direct atomic structure by multiple-energy inversion of experimental forward-scattering-photoelectron and Auger-electron-diffraction data

Abstract

We demonstrate multiple-wave-number reconstruction of experimental data for forward-scattering-photoelectron and Auger-electron-angular-diffraction distributions of Cu(001). Direct structural information of the nearest- and next-nearest-neighbor atoms is obtained. The structure so determined provides a useful starting point for refinement by diffraction methods, thus avoiding the cumbersome trial-and-error process.
