| Description | It is explained that, contrary to the traditional Loeb- Alexandrov model for the negative corona current pulses formation, the more recent streamer-based model admits the existence of a significant free electron current in negative corona discharges burning in ambient air even at distances from the cathode on the order of 1–10 mm. The existence of such free electrons is in a sharp contrast to the commonly held belief that the low-field drift region of the discharge is filled solely with the negative ions. The importance of such free electrons for chemical reactions induced by negative corona discharges is discussed briefly. |
