Measurements of Townsend's Energy Factor k1 for Electrons in Carbon Dioxide

Abstract

Values of Townsend's energy factor kl for electrons in carbon dioxide have been determined as a function of the parameter E/p for 0�1 .;;; E/p .;;; 50 at a temperature of 293�K. The results are compared with those of other investigators and are used in a recomparison of the cross sections for electron attachment deduced from swarm and beam types of experiments for swarms of electrons having mean energies of up to 5 eV.
