Analysis of Recoil Ion Momentum in Ne(e, 2e)Ne+ Reaction

Using cold target recoil-ion momentum spectroscopy (COLTRIMS) we have measured the momenta of recoil target ions in the single ionization (e, 2e) reactions of Ne at the energies between 70 and 3300 eV. A simple collision mechanism was introduced to analyze the distributions of the momenta of recoil ions. This mechanism can qualitatively well explain the distributions for the intermediate and high impact energy. Finally, the energy range of the ionized electron according to the momenta of the ion was estimated,which lays the foundation for the next coincidence measurement of electrons and ions. (authors)
