DRIFT VELOCITIES AND CHARACTERISTIC ENERGIES OF ELECTRONS IN DEUTERIUM AT LOW AND MODERATE E N/

The measurements of the drift velocities and characteristic energies o f electrons in deuterium are presented. Drift velocities are obtained between 3 and 125 Td by a standard Bradbury-Nielsen technique with a d ouble set of shutters. The characteristic energy for the transverse di ffusion was measured by a standard Townsend-Huxley technique to be bet ween 3 and 1000 Td. The drift velocities and characteristic energies a re in good agreement with the best available data in the range of over lap and extend the availability of the experimental data to higher E/N . The predictions based on the best available cross section sets do no t match the experimental results at higher E/N above the limits of the previously available data.
