It is shown that the multichannel problem of the recombination of an electron and a molecular ion can be rigorously reduced to the determination of an optical potential for the elastic scattering of an electron by a molecular ion. A method, based on the formalism of many-particle theory, is proposed and makes it possible to construct the optical potential. As a result, formulas are derived for the reasonance part of the dissociative-recombination cross section with allowance for strong channel coupling. These formulas are used to calculate the cross section for dissociative recombination of an electron and a molecular-oxygen ion in various vibrational states. All the quantities in the formula for the cross section are determined by the present method, and are not adjustable parameters. The results are in satisfactory agreement with the experimental data.
