Abstract
A crossed beam study of CO + production from the C + + O 2 reaction at a collision energy of 0.57 eV is presented. Very clear collision complex dynamics are observed which are shown to be consistent with the decay of a transient complex having a lifetime of approximately 0.5 ps. An analysis of the reactive scattering using an adiabatic state correlation diagram indicates that the formation of X-state CO 2 + by insertion of C + into the O 2 bond is accessible from the reagents and correlates adiabatically with ground-state products. The average kinetic energy release is approximately 23% of the available energy. A comparison of the present data with the chemiluminescent studies of A-state production of CO + indicates that the dominant channels at low energies are production of ground-state CO + through the X 2Π g and a 4Π u state of CO 2 +.
