Observation of a large dose rate effect on the ozone yield in the radiolysis of gaseous oxygen

The ozone yield from the radiolysis of gaseous oxygen has been measured to be G(O3) = 12.8 ± 0.6 at 1026–1027 eV g−1 s−1 and to be G(O3) = 6.2 ± 0.6 at 1016 eV g−1 s−1. The latter result depends on a new determination of the stoichiometry of the oxidation of iodide by ozone. It is proposed that the difference in yields between the two dose rates is due to differences in ion-recombination processes.
