Swarm derived electron collision cross section set for the perfluorocyclobutane molecule

Abstract

The cross section set of perfluorocyclobutane (c-C4F8) is determined by the electron swarm method. The modification is applied to the vibrational excitation cross section and the elastic momentum transfer cross section. Our previously measured electron swarm parameters (drift velocities, longitudinal diffusion coefficients and effective ionization coefficients) in 0.468% and 4.910% c-C4F8/Ar mixtures are used for the determination of the vibrational excitation cross section. The measured drift velocity and longitudinal diffusion coefficient in pure c-C4F8 are used to determine the correct elastic momentum transfer cross section. The calculated electron transport coefficients were derived using the Monte Carlo simulation method.
