Abstract: We report the measured total charge-transfer (electron-capture) cross sectionsfor the ground state O₂⁺ (X²πg) ions with H₂ and O₂ molecular gases in the collisionenergy range between 0.50 and 2 keV. The time-of-flight technique has been used tomeasure the fast neutral products from O₂⁺ charge transfer reactions. The analyzedprocess has cross sections that continue to increase slowly, as a function of incidentenergy. Measured cross sections for O₂⁺ H₂, O₂ systems are compared with previouslyavailable experimental and theoretical results in the literature.

Keywords: Single electron-capture; total cross-sections
