Triple-differential ionization cross sections {ital d}{sup 3}{sigma}/{ital d}{var theta}{sub {ital p}dcphi{ital p}dprec}, the momentum distributions of singly charged recoil ions transverse to the beam direction as a function of the projectile polar ({var theta}{sub {ital p}}), and azimuthal ({ital cphi}{sub {ital p}}) scattering angle were measured in order to elucidate the dynamics of 3-MeV H{sup +} on He single ionization. For projectile polar deflections 0.2 {le}{var theta}{sub {ital p}}{le}1 mrad and azimuthal scattering angles 0{sup {degree}}{le}{ital cphi}{sub {ital p}}{le}360{degree}, the kinematic regimes where two-body interactions dominate the three-body momentum exchange of the single-ionization reaction were separated experimentally.
