Abstract

We measured the drift velocity and the longitudinal diffusion coefficient of electrons in pure C₂H₂. The present drift velocity in the lower E/N agreed very well with the measurement of Duncan and Walker, but there are no comparative results with our data in higher E/N range. The longitudinal diffusion coefficient of electrons in pure C₂H₂ is the first measurement. We also measured these transport parameters in the 0.517 % and 5.06 % C₂H₂-Ar mixtures over wide E/N ranges in order to evaluate the existing set of the electron collision cross sections for the C₂H₂ molecule.
