Abstract : Rate coefficients for formation of N2, NO, H2, HO2, H2O2, He2(+), and Ar2(+) from atoms, atomic ions, or free radicals in triple collisions were measured at 300 K. A theoretical evaluation of the rate coefficient for diatomic molecule formation in triple collisions was carried out, giving results which agreed well with the experimental values. Rate coefficients for several bimolecular reactions involving O atoms, N atoms, or OH radicals were also determined. A theory of positive ion collection by Langmuir probes in gas discharge plasmas at pressures between about 0.1 and 20 mm Hg was developed. Dissociative recombination coefficients of Ar, N, O, Hg, and Cs molecular ions were determined from probe measurements on gas discharge afterglows, using this theory to calculate ion concentrations from probe currents. Recombination coefficients obtained in this manner agreed well with values obtained by microwave techniques. (Author)
