Abstract

Electron drift velocities in mixtures of SiF₄ and Ar have been measured using a pulsed‐Townsend type drift tube. A set of vibrational excitation cross sections of electron scattering in SiF₄ has been subsequently determined by the swarm analyses of measured transport data in highly dilute SiF₄−Ar mixtures. The derived cross sections are consistent with the electron transport properties over an order of magnitude in SiF₄ concentration in gas mixtures, thus providing evidence that the main features of their near threshold behavior, and of their absolute magnitude have been captured.
