Application of a novel multiple scattering approach to photoelectron diffraction and Auger electron diffraction

Path-reversed Auger electron and photoelectron diffraction

We propose a method for the computer simulation of Auger electron and photoelectron diffraction patterns by evaluating the amplitude of propagation paths from the detector to the electron-emitting source, justified by Helmholtz’s reciprocity principle. The method offers significant computational advantages over previous schemes, and suggests an easy extension to enable the calculation of a stru...

This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite targets, and are available both as single crystals and in polycr...

X-ray photoelectron diffraction study of Cu(111): Multiple scattering investigation

Multiple scattering theory based on a cluster model is used to simulate full-hemispherical X-ray photoelectron diffraction measure ments in order to verify how state of the art multiple scattering simulations are able to reproduce the experiment. This approach applied to the Cu(111) surface for two different photoelectron kinetic energies. Differences and similarities between single and multip ...

Elastic and Inelastic Scattering in Electron Diffraction and Imaging Introduction

Electron Diffraction

In this equation, h is Planck’s constant and E = p/(2m) is the kinetic energy of the particle in the non-relativistic regime. The wave aspect of particles was demonstrated first by an experiment on electron diffraction performed by C. H. Davisson and L. H. Germer. For his hypothesis on the wave nature of particles de Broglie was awarded the Nobel Prize in Physics in 1929, and Davisson and Germe...
