Internal energy effects in the reactivity of CO2 2+ doubly charged molecular ions with CO2 and CO.
Original language description
Reactivity of the dication CO22+ in dependence on its internal energy was studied in collisions with CO2 and CO. The dication was obtained by photoionization of the CO2 molecule by synchrotron radiation and the guided beam apparatus CERISES was used in these studies. Spontaneous dissociation of CO22+ to CO+ and O+ was observed without any target gas in the reaction cell. With CO2 or CO as a target gas, fragment ion CO+ and O+ were formed as products of dissociative charge transfer, while the contribution of collision induced dissociation of the reactant CO22+ to their formation was found negligible. The CO+ yield showed a considerable dependence on the internal energy of the reactant dication CO22+: the branching ratio CO+/O+ increased gradually with photon energy between 38.5 and 40 eV. We interpret this observation as being due to the increase in the accessible.
