Radiolysis of air and nitrogen-oxygen mixtures with intense electron pulses: determination of a mechanism by comparison of measured and computed yields
Air and other mixtures of nitrogen and oxygen containing from 0.1 to 100% oxygen have been irradiated with single, 0.12 Mrad electron pulses at a dose rate of 2 × 10 26 eV g −1 s −1 . The major product formed in these irradiations is ozone. For air from 400-1500 Torr, G(O 3 ) = 10.3 ± 0.5, the addi...
