We present classical trajectory Monte Carlo calculations of differential cross sections for direct ionization (without charge transfer) of He by protons, electrons, and their antiparticles at 200 keV/amu. Dynamical effects depending on the charge-sign and mass of the projectiles, as elucidated by ...
