STUDIES AND EXPERIMENTAL WORK ON ATOMIC COLLISION PROCESSES OCCURRING IN ATMOSPHERIC GASES
Abstract
Temperature dependent recombination studies in nitrogen were conducted over the range 200-480K, yielding a coefficient of (2.9 plus or minus 0.3) x 0.0000001 cu cm/sec for the recombination of N2(+) ions and electrons. The observed temperature dependence is quite small, being adequately described by the relation T exp.-0.02. Several modifications have been made on the flow system used in the study of associative detachment in O2-O mixtures. In subsequent studies a reaction resembling associative detachment was observed. While preliminary tests were being conducted on the rf mass spectrometer which is to be used on the flow system, a brief study of negative ion-molecule reactions was made. Rate coefficients for several of these reactions were measured. A summary of the results of a calculation of momentum transfer and inelastic cross sections for electrons in oxygen is presented. The computed momentum transfer cross section is in satisfactory agreement with electron beam results but it differs significantly from the cross section obtained at thermal energies from microwave experiments.
