The yield of oxygen and hydrogen atoms through dissociative recombination of H2O+ ions with electrons

Abstract
The branching ratios of the dissociative recombination of excited H2O+ ions with electrons were studied using a plasma flow tube experiment. The total oxygen atom channel accounts for 45% of the recombination with more than 24% in O+H+H. The remaining channel is OH+H for 55%. These results are discussed in comparison with the few available theories and with photodissociation data.
