Cross sections for ion formation in C + O2 collisions have been measured as a function of kinetic energy up to 15 eV. Charge transfer gives rise to C+, O2-, C+, O2-, and free electrons. Five processes leading to these products has been identified. Reactive ionisation is taking place according to three processes: C + O2 -> CO+ + O + e-; CO+ + O-; CO + O+ + e-.
