This process, however, requires a large concentration of negative ions. Loeb (1965) carried out experiments on electron detachment in oxygen and found that it occurs for E / p = 68V/m*Pa. In compressed electronegative gases suchas Sulfr hexafluoride, detachment has been considered as one of the main processes involved in breakdown phenomena over a wide rangeGet price
