The research performed has been in the area of low energy crossed ion beam-neutral beam studies of a wide spectrum of elementary chemical reactions. Our reactive scattering work embodies crossed beam studies of simple chemical processes under single-collision conditions which elucidate reaction dynamics by measuring product branching ratios, translational energy distributions and scattering angle distributions. The studies have emphasized the proton transfer reactions of the important flame cations HCO/sup +/ and H/sub 3/O/sup +/ with a number of neutral molecules present in flames, including H/sub 2/O, CH/sub 3/OH, CH/sub 3/CH/sub 2/OH, and (CH/sub 3/)/sub 2/CO, and a wide variety of reactions of the ground state carbon cation, C/sup +/(/sup 2/P), with neutrals, illustrating the important reactions of insertion into C-H, O-H, N-H, and C-C bonds, as well as condensation reactions in which new C-C bonds are formed, yielding significant increases in the molecular weight of the charged product. These studies represent the first crossed-beam studies in which information more detailed than rate constants and energy dependent total cross sections has been inferred about the reaction dynamics. The differential cross section measurements we have performed during the last three years represent the only extant data of this type and yield unique insight into several classes of chemical reactions over a wide range of collision energies.
