Sideband diffraction: A prediction of the quantum field theory of inelastic low-energy electron diffraction from solids

A quantum field theory of inelastic electron diffraction is proposed and utilized to calculate the differential inelastic scattering cross section in fourth-order perturbation theory. The vestiges of momentum conservation normal to the surface cause the occurence of a new phenomenon: sideband diffra...

Description
Summary:A quantum field theory of inelastic electron diffraction is proposed and utilized to calculate the differential inelastic scattering cross section in fourth-order perturbation theory. The vestiges of momentum conservation normal to the surface cause the occurence of a new phenomenon: sideband diffraction. Eine quantisierte Feldtheorie für die inelastische Elektronenstreuung wird vorgeschlagen und angewendet, um den differentiellen inelastischen Streuquerschnitt in vierter Ordnung der Störungsrechnung zu berechnen. Weil der Impuls senkrecht zur Oberfläche nicht erhalten bleibt, tritt ein neues Phänomen ein: die Seitenbandstreuung.
