Abstract
A detailed study of the differential cross section for the elastic scattering of electrons by helium at intermediate and high energies has been made. In this study a theoretical procedure, recently suggested by one of the authors (J.N.D.), has been followed. The calculated differential cross sections in the energy range 100-200 eV appear to be in very good agreement with experiment and better than the existing theoretical results. At higher energies, the present results are also better except at very small angles where the eikonal-Born-series results of Byron and Joachain are better. The scattering amplitudes obtained during this calculation have also been presented.Keywords
