The ionization cross sections for N/sub 2/ and O/sub 2/ molecules on impact with N/sub 2/ and O/sub 2/ molecules have been measured over the laboratory energy range from 20 to 1000 ev. The inci-dent molecular beams were produced by the technique of ionization by electron impact, electrostatic acceleration, and neutralization by charge transfer. The measurements were carried out in a low-pressure parallel plate ionization chamber. Particular attention was paid to the problem of secondary electrons. Ionlzation was observed a few ev above threshold for all combinations. Cross sections which were obtained ranged from 10/sup -20/ to 5 x 10/sup -16/ cm/sup 2/. The N/su b 2-/ O/sub 2/, O/sub 2/-- N/sub 2/, and O/sub 2/-O/sub 2/ curves of cross section vs incident particle energy showed no apparent structure, as contrasted with N/sub 2/-N/sub 2/ case. The N/sub 2/-O/sub 2/ and O/sub 2/-N/sub 2/ results were in agreement when corrected to center-of-mass energy. (auth)
