Inelastic scattering of vortex electrons beyond the Born approximation
S. Strnat, J. Sommerfeldt, A. K. Sahoo +2
We present a theoretical study of the inelastic scattering of vortex electrons by a hydrogen atom. In our study, special emphasis is placed on the effects of the Coulomb interactio…

Delbrück scattering above the pair production threshold: Going beyond the Born approximation
J. Sommerfeldt, V. A. Yerokhin, A. Surzhykov
We present a theoretical method to calculate Delbrück scattering amplitudes for photon energies above the electron-positron pair production threshold. The method is based on the ap…
