Recent Progress in High Resolution Proton-Molecule Charge Transfer Scattering Studies
Vibrational state resolved scattering experiments on the charge transfer collisions of H+ with H2, CO2, O2, and H2O target molecules are reported at collision energies of about 30 eV. The results are discussed in terms of simple models, which are based on the simultaneous availability of the scattered H+ and H total angular distributions as well as their time-of-flight spectra in dependence on the scattering angle, 0°≦θ≦15°. They provide a detailed insight into the vibrational interaction dynamics with respect to the relative importance of energy resonance and the role of the Franck-Condon factors in determining the charge transfer transition probabilities to the final vibrational states. In addition, the dependence of these probabilities on the particular vibrational excitation of the neutral molecule by the time-dependent proton electric field can be studied in great detail.
