Electron-hydrogen elastic scattering in the eikonal approximation

Abstract
Differential and total cross sections for elastic scattering of electrons from atomic hydrogen have been calculated using the full eikonal approximation. The eikonal results for 50-, 100-, and 200-eV incident electrons are compared with other theoretical calculations and with recent experimental data. It is found that the full eikonal approximation predicts both small-angle differential cross sections and total cross sections, which are in better agreement with experiment than either the Born or Glauber results.
