REACTIONS OF O(+) IONS IN HELIUM-OXYGEN AND HELIUM-OXYGEN-NITROGEN MIXTURES.
Abstract
Observations are reported concerning the decay of O(+) ions in helium-oxygen mixtures over the approximate temperature range 200 - 600K and in helium-oxygen-nitrogen mixtures at 300K. From these observations, values for k sub O and k sub N, the rate coefficients for the reaction of O(+) ions with molecular oxygen and molecular nitrogen respectively, were obtained. The values at 300K are: k sub O = (2.0 +0.4 or -0.3) x 10 to the -11th power/cc/sec; k sub N = (2.4 plus or minus 0.4) x 10 to the -12th power/cc/sec. Over the temperature range 200 - 600K, k sub O is shown to be related to the temperature by the equation: k sub O = 3.5 x 10 to the -10th power (T to the -1/2 power)/cc/sec. These results are compared with measurements obtained by other workers and the ionospheric implications of these results are discussed. (Author)
