Electron and positron scattering by atomic beryllium

We present calculations of cross sections for electron- and positron-scattering from atomic beryllium over a wide range of incident energies from the first inelastic thresholds to 5000 eV. We use model potentials that have been shown to be reliable over a wide energy range in previous studies. The present work includes the total, integrated elastic, momentum transfer, and differential cross sections. In addition, we have found several critical minima in the differential cross sections for both electron and positron scattering
