Abstract
Triple-differential ionization cross sections σ/d , the momentum distributions of singly charged recoil ions transverse to the beam direction as a function of the projectile polar (), and azimuthal () scattering angle were measured in order to elucidate the dynamics of 3-MeV on He single ionization. For projectile polar deflections 0.2 ≤≤1 mrad and azimuthal scattering angles ≤≤360°, the kinematic regimes where two-body interactions dominate the three-body momentum exchange of the single-ionization reaction were separated experimentally.
