Dissociative recombination of electrons and O2+ molecular ions in the field of intense visible laser radiation

We analyze the low-temperature dissociative recombination reaction e(-) + O-2(+) --> O(D-1) + O(P-3) in the field of visible monochromatic laser radiation. The analysis is performed in terms of the multichannel quantum defect theory using the stationary formalism of the radiative collision matrix. We calculate the dependences of the reaction cross section on the incident electron energy, the external electromagnetic field strength and frequency, and also the angle between the directions of the electron beam and the electric vector for linearly polarized radiation. The cross section is shown to increase by several orders of magnitude for a certain choice of these parameters, suggesting the possible laser stimulation of this reaction.
