Abstract

Electron drift velocities in mixtures of SiF 4 and Ar have been measured using a pulsed&hyphen;Townsend type drift tube. A set of vibrational excitation cross sections of electron scattering in SiF 4 has been subsequently determined by the swarm analyses of measured transport data in highly dilute SiF 4 −Ar mixtures. The derived cross sections are consistent with the electron transport properties over an order of magnitude in SiF 4 concentration in gas mixtures, thus providing evidence that the main features of their near threshold behavior, and of their absolute magnitude have been captured.
