Electron-electron interaction in projectile ionization investigated by high resolution recoil ion momentum spectroscopy

Electron-electron interaction in projectile ionization investigated by high resolution recoil ion momentum spectroscopy

Contributions of the electron-electron and the nuclear-electron interactions to projectile electron loss in He[sup +] on helium collisions have been clearly separated kinematically for the first time by measuring the longitudinal and transverse momenta of the recoiling target ion with precision of b...

Zusammenfassung:Contributions of the electron-electron and the nuclear-electron interactions to projectile electron loss in He[sup +] on helium collisions have been clearly separated kinematically for the first time by measuring the longitudinal and transverse momenta of the recoiling target ion with precision of better than [plus minus]0.15 a.u. The longitudinal and transverse momentum distributions are in general agreement with two-center [ital n]-body classical trajectory Monte Carlo calculations.
