A new experimental method has been developed which allows determination of the products nature in dissociative recombination (D.R.) of molecular ions. Results are presented on H2O+ D.R. which show that there is a large yield of oxygen atoms in this reaction. the measurements give a total yield for the two channel O + H + H and O + H2 of 0.45 and therefore a yield of 0.55 for OH + H. H2O+ ions are formed by charge exchange from N+ ions and are probably vibrationally excited in this experiment.
