New Atomic Beam Studies at Low Energies.

Final cross sections have been obtained for charge transfer between the ions O and N and the neutral atoms uranium and thorium. In the course of these measurements, cross sections were also obtained for some of the other charge transfer reactions. A second task completed was the measurement of cross sections for the reaction of Al with molecular nitrogen and oxygen. Attempts were made to measurem cross sections for other processes involving these reactants but no measurable signals could be detected. A final set of experiments involved a search for a route for formation of H3O using NO as a precursor. No conclusive evidence for such a process could be found in the energy range covered by the experiments.
