Electron Attachment in Oxygen†

Processes of electron detachment in Townsend discharges in oxygen ore discussed and, it is suggested, are negligible for pressures greater than very approximately 1OO—200 mm Hg in the range of values of the parameter E/P(≯E/P∼50 v/cm/mm Hg) used in the experiments. At lower pressures, in agreement with Frommhold's recent work, detachment becomes important particularly at higher values of E/p.
