Abstract:

Laboratory studies have been made of the positive and negative ions resulting from the irradiation of airlike N2O2 mixtures at total pressures between 1 and 8 Torr by megavolt electrons. For gas mixtures containing less than 1 ppm H2O, only O2, and O2- are observed at the onset of irradiation as the electron bombardment continues, these ions interact with beam-generated minority species to produce an ion spectrum eventually dominated by NO, NO2- , and NO3-. Quantitative studies of the removal of O2 by charge-exchange with beam-generated NO yield for the dominant NO-producing mechanism the reaction O2 N2 yields NO NO. If H2O concentrations between 5 and 20 ppm are added to the gas, the positive ion spectrum observed after long irradiation is dominated by complex ions of the form H3O.n H2ON 0, 1, 2, . .., in agreement with in situ observations in the D region.
