The dynamics of the reaction of Xe/sup +/ + CH/sub 4/ ..-->.. XeH/sup +/ + CH/sub 3//sup +/ were studied with chemical accelerator techniques over the energy range 0.2 to 8.0 eV. Kinematic measurements were used to give information on the reaction mechanism and the partitioning of product energy between internal and translation modes. The results suggest the reaction mechanism changes from long lived complex formation at energies below 0.5 eV to a direct mechanism approaching spectator stripping at higher energies. The dynamics for reactions of the type A/sup +2/ + B ..-->.. A/sup +/ + B/sup +/ were also investigated by this same technique for ions of Kr and Ar incident on Ne and CH/sub 4/, respectively, and both on N/sub 2/. Ionization potential spectra were constructed for the neutral species from the kinematic data. Comparison of these spectra with similar spectra from photoelectron spectroscopy led to the desire to investigate their vibrational structure. To this end a hemispherical energy analyzer was constructed and tested that should provide the narrower energy dispersion in the ion beam and translational energy spectrum resolution needed to help make this further investigation possible.
