Electron-Capture Cross Sections of Ground-State O(2)(+) Recoil Ions in Slow Collisions with H(2) and O(2)

We report the measured total charge-transfer (electron-capture) cross sections for the ground state [Formula: see text] ions with H(2) and O(2) 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 [Formula: see text] charge transfer reactions. The analyzed process has cross sections that continue to increase slowly, as a function of incident energy. Measured cross sections for [Formula: see text] , O(2) systems are compared with previously available experimental and theoretical results in the literature.
