Abstract

"The charge transfer reactions of 0^-, S^- with atomic hydrogen were studied from 1.5 to 10 KeV, and the reaction Cl^- + O₂ + O₂^- + Cl was studied from 10 eV to 10 KeV. The reactions studied were normalized to the reaction H^- + H + H + H^-. The maximum measured cross sections were 4.6 x 10^-16 cm² for the reaction Cl^- + O₂ + O₂^- + Cl and 4.4 x 10^-15 cm² for the reaction 0^- + H + H- + 0 and 1.6 x 10-15 cm2 for the reactions-+ H + H^- + S. The results are compared to a modified theoretical treatment for positive ions of Rapp and Francis⁵¹ with some success.

A crossed beam technique was used to perform these measurements. The ion beam was produced by a conventional hot anode arc discharge. The neutral beam was produced by a joule heated tungsten oven. Counting techniques were used in the data collection" -- Abstract, p. ii
