Transport parameters of electron swarms in nitrogen at moderate and elevated E/N

By means of the Blevin-Hasan version of the Bradbury-Nielsen technique and Townsend-Huxley method, the drift velocity W, characteristic energy D/mu and the D-L/mu parameter have been determined at ambient temperature for reduced electric fields 300 less than or equal to E/N less than or equal to 500 Td, 30 less than or equal to E/N less than or equal to 1000 Td and 250 less than or equal to E/N less than or equal to 1000 Td, respectively. The present results have been compared with experimental and theoretical ones of other investigators.
