Abstract:	We report the measured total charge-transfer (electron-capture) cross sections for the ground state $O_{2}^{+} (X^{2} Π_{g})$ ions with H₂ and O₂ molecular gases in the collision energy range between 0.50 and 2 keV. The time-of-flight technique has been used to measure the fast neutral products from $O_{2}^{+}$ charge transfer reactions. The analyzed process has cross sections that continue to increase slowly, as a function of incident energy. Measured cross sections for $O_{2}^{+} + H_{2}$ , O₂ systems are compared with previously available experimental and theoretical results in the literature.

Keywords:	Single electron-capture total cross-sections
