Transmission resonance diffraction and low impact parameter inelastic scattering of high-energy electrons

Abstract

Since the development of the theoretical treatment of transmission (bulk) resonance scattering of high-energy electrons it has been anticipated that this type of many-beam diffraction could lead to a substantial increase in the cross-section of all inelastic interactions characterized by small impact parameters of electron-atom collisions. However, until recently ring Kikuchi patterns remained the only existing confirmation of this prediction, showing the increase of the cross-section of thermal diffuse scattering due to resonance diffraction in the final state of the process of inelastic interaction. In this paper we report the results of the first experimental observation showing the incre..
