Abstract

We present measured and calculated differential cross sections, as well as calculated integral cross sections, for elastic electron collisions with CH_3F, CH_2F_2, CHF_3, and CF_4. The calculated cross sections were obtained with the Schwinger multichannel method, and a Born-closure procedure was used to improve the differential cross sections for polar systems. Polarization effects were found to be relevant even for systems with moderately large permanent dipole moments, such as CH_3F and CHF_3. In general, there is good agreement between theory and experiment.
