Abstract

The electron drift velocity and the density-normalized longitudinal diffusion coefficient in the pure C2F6 molecule over the E/N range of 0.1-100 Td have been measured using a double shutter drift tube, where E is the electric field and N is the neutral number density. Our electron drift velocity values are in good agreement with those reported in a previous work on the C2F6 molecule. The negative differential conductivity phenomenon was found in the electron drift velocity. The results of our new measurements on the pure C2F6 molecule, along with the available electron transport coefficients, in 0.524 and 5.47 % C2F6 - Ar mixtures were used to successfully obtain the most reliable set of electron-collision cross sections for the C2F6 molecule by using a multi-term Boltzmann analysis.
