Abstract

Using a solid Xe matrix upon a cold finger, at temperatures less than 77 K, O(1S) metastables produced from electron impact dissociative excitation of H2O, D2O, and NO were observed. From time-of-flight observations, total released kinetic energy spectra for the dissociative channels were ascertained. Threshold energies for dissociative channels were measured. Using the relative flow technique [Trajmar et al. (1996)], cross sections for the production of O(1S) from electron impact dissociation of H2O and D2O were made absolute by comparison with cross sections for O(1S) production from electron impact dissociation of CO2. In the case of H2O/D2O, the dissociative channels were uniquely identified based on the detection of an O(1S) fragment, observed threshold energies, required symmetry arguments for optically allowed transition and the absence of angular momentum in the resultant fragments.
