The O+(S-4)+NO(X (2)Pi(r)) collision system has been investigated in a guided-ion beam experiment. Absolute cross sections for production of NO+ and O-2(+) have been measured at collision energies from near thermal to similar to 12 eV. Time-of-flight measurements of the NO+ product recoil velocities, at collision energies of 1.3, 3.3, 5.2, and 9.1 eV confirm two hyperthermal charge transfer channels with thresholds at 0.2 and 2.0 eV. A kinematic analysis indicates mechanisms that give rise to spin-forbidden NO+(X (1)Sigma(+))+O(D-1) and endothermic NO+(a (3)Sigma(+))+O(P-3) products, respectively. The O-2(+)+N channel is observed to have a threshold of 0.7 +/-0.1 eV. Time-of-flight studies of the O-2(+) product at collision energies of 3.3 and 5.9 eV indicate a complex-mediated mechanism.
