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 ener gy D/mu and the D-L/mu parameter have been determined at ambient tempe rature 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 equ al 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 exp erimental and theoretical ones of other investigators.
