Abstract
The angular distribution of electrons ejected from He with about the projectile velocity in coincidence with the capture of the other electron by the projectile in 1-MeV proton-He collisions has been measured. The signature of the proton-electron-electron scattering leading to transfer ionization has been observed for the first time as a peak at about 90° in the angular distribution of the ejected electrons. The effect is in qualitative agreement with theoretical predictions.Keywords
