Double electron transfer reactions of CO22+ ions

Time-of-flight techniques have been used to measure fast neutral CO2 products from double electron transfer reactions of CO22+ ions with 4.0–7.0 keV impact energies. Double electron transfer cross sections have been determined to be in the range of (1.1–12.5) × 10−16 cm2 for reactions of CO22+ ions with CO2, CO, N2, Ar and O2.
