Abstract
The triply differential cross section for the single ionization of helium by 500-eV electrons has been measured in a coplanar asymmetric geometry and analyzed by using a second Born-approximation treatment. It is found that these theoretical predictions concerning the angular positions, shapes, and magnitudes of both the binary and recoil peaks are in good agreement with experiment.Keywords
