Electron-Electron Interactions in Ion-Atom Collisions Studied by Energy-Loss Spectroscopy

Abstract

We have performed a series of experiments on the University of Missouri-Rolla ion energy-loss spectrometer to study the role of electron-electron interactions in ion-atom collisions. In one experiment we have taken energy-loss spectra for 50 keV protons colliding with He. From the data we obtained cross sections for double excitation of the target atom. In a second experiment we measured coincidences between neutralized projectiles and target recoil ions in p + He collisions at projectile energies of 50 and 100 keV. From these data we obtained the ratio of transfer ionization to single capture as a function of the projectile scattering angle. In a preliminary experiment we also used this coincidence technique for projectiles which did not undergo charge exchange and which were energy analyzed to study single and double ionization.
