Abstract:

Research results concerning atmospheric ion reactions are briefly summarized. Measurements of the coefficients of recombination of electrons with positive ions of the H3O.H2On series have been carried out. Clustering of NO ions to N2 and to H2O has been studied to clarify the cluster-switching sequence responsible for D-region production of H3O.H2On series ions. Reaction rates of O with N2 and O2 to form NO and O2 at high ion temperatures F-region conditions have been determined. Ionization and electron heating by metastable atoms have been studied in very pure helium afterglows. Modified author abstract
