Title: Ion-Molecule Reactions and Ion Energies in CF4 Discharges
Published: December 01, 1999
Abstract: Absolute cross sections have been measured for reactants typically found in carbon tetrafluoride (CF4) discharges for collision energies below a few hundred electron volts. The reactions investigated include collision-induced dissociation and dissociative electron transfer reactions for CF3+ and F+ colliding with CF4, and collisional electron detachment for F- colliding with CF4. Also presented are measurements of energies and relative intensities of ions generated in dc Townsend CF4 discharges with E/N values ranging from 4 x 10-18 V m2 (4 to 25 kTd). Ion energy and ion intensity data for the Townsend discharges are analyzed in light of the measured cross sections.
