Corona discharge the electron-liberation is a high-energy photon from an atom within the plasma body relaxing after excitation from an earlier collision. The use of ionized neutral gas as a source of ionization is further diminished in a negative corona by the high-concentration of positive ions clustering around the curved electrode. Under other conditions, the collision of the positive species with the curved electrode can also cause electron liberation. The difference, then, between positive and negative coronas, in the matter of the generation of secondary electron avalanches, is that in a positive corona they are generated by the gas surrounding the plasma
Negative and positive atheism Smith as synonyms of the less-well-known categories of implicit and explicit atheism, also relating to whether an individual holds a specific view that gods do not exist. ""Positive"" atheists explicitly assert that it is false that any deities exist. ""Negative"" atheists assert they do not believe any deities exist, but do not explicitly assert it is "true" that no deity exists. Those who do not believe any deities exist, but do not assert such non-belief, are included among "implicit atheists". Among "implicit" atheists are thus included the following: children and adults who have never heard of deities; people who have
