Abstract : Measurements made on the selected-ion flow-tube at the Air Force Geophysics Laboratory on the temperature dependence of several ion-molecule reaction rate coefficients. The N(+) + CO and C(+)+ NO systems were studied over a range of 9 - 450 K. Measurements were also made on C(+) + O2, CO+ + O2, and CO2(+) + O2 over the range 90 - 450 K. Comparison with available earlier results showed agreement within experimental uncertainty. A flowing afterglow apparatus was developed at Oklahoma for the study of ion interactions. Positive-ion/negative ion recombination was studied in this apparatus. Preliminary work was carried out for the Cl2(+) + Cl system and photographic documentation is used to determine the strength of the recombination process. (Author)
