Total charge-transfer cross sections have been measured for reactions of 0.8-3.0-keV ground-state O2+(X2IIg, u') ions and long-lived, excited-state Oz+(a411,, u') ions with Hz, N2, CO, COO, Oz, NO, and Ar. Time-of-flight techniques have been used to measure the fast neutral O2 products from charge-transfer reactions. These reactions have been examined as a function of electron energy used to produce the reactant ions and cross sections have ...
