A crossed molecular beam apparatus for the study of low energy ion-molecule reactions and free-radical chemiionization kinetics was constructed, and its initial work was in the study of reactions of H/sub 2//sup +/ + CO, N/sub 2/, and Ar at energies between 5 and 10 eV. The preliminary results obtained indicate that in the energy range studied, the reactions proceed via impulsive, direct collisions. The molecular ion products are scattered in the backward direction with respect to the incoming H/sub 2//sup +/ projectile with translational energy in excess of that predicted by spectator stripping. Also completed was the construction of a discharge ion-source with a sample vaporization compartment, allowing solids and liquids to be used as source materials. This source will be used to prepare HCO/sup +/ beams for studies of reactions such as HCO/sup +/ + H/sub 2/O/sup +/ H/sub 3/O/sup +/ + CO, considered important in hydrocarbon flames.
