    Electron-impact ionization of helium has been studied in the energy range from 3-10 eV above the ionization threshold by measuring (e, 2e) angular correlations over a wide range of scattering angles from the coplanar to the perpendicular plane geometry. In these measurements the two outgoing electrons are observed at symmetric scattering angles and with equal energies.
