Ozone Formation and Ion Chemistry in Oxygen Radiolysis

Detailed electron-impact and chemistry calculations have been carried out for situations corresponding to a number of published oxygen radiolysis experiments. The results fit the measured ozone production values within 25 percent, provided that the neutralization reaction of Oxygen sub 4 with oxygen sub 2 - yields two oxygen atoms, while the neutralization of Oxygen sub 4 or Oxygen sub 5 by Oxygen sub 3 yields no odd oxygen species 0 or 03 expect for that already present in the ions. In addition, to explain the steady-state ozone concentration attained by long duration irradiation, the reaction Oxygen sub 3 Ozone second 2 oxygen sub 2 at room temperature and probably a temperature dependence of about exp -1000T.
