Measurements of total cross sections for collision induced dissociation (CID) and proton abstraction have been made for the reactants H-3(+) + H-2, Ar, and He. The laboratory collision energies range 3 from a few up to 400 eV and D-3(+) has been substituted to investigate possible isotope effects. The CID cross sections of H-3(+)-->H++H-2 Or H-2(+) + H maximize at a value of a few Angstrom(2). Proton abstraction is the dominant process for relative collision energies below 5 eV and is observed to lead to a highly excited H-3(+) product which often autodissociates. Dissociative charge transfer at higher collision energies is responsible for producing H : product ions. The role of internal energy contained within the H-3(+) primaries in previous experiments and the effects of internal energy on the cross section measurements presented here are also discussed.
