Abstract
Electron impact ionization of helium in a symmetric coplanar energy-sharing geometry at 45° angle is investigated in the incident energy range 45 eV to 500 eV. The results of coincidence experiments are put on an absolute scale by normalisation to known elastic scattering cross sections. Comparison is made with calculations in the plane-wave and distorted-wave Born and Impulse approximations.
