Abstract
We present a combined experimental and theoretical study of 32.6-eV electron-impact ionization of helium. The measured absolute coplanar triply differential cross sections are in the equal-energy-sharing kinematical region, and have been obtained in the fixed fixed and symmetric geometries. The convergent close-coupling calculations are in excellent agreement with experiment.
