An Annotated Compilation and Appraisal of Electron Swarm Data in Electronegative Gases

Abstract
Available data on the electron transport properties and electron swarm coefficients are discussed for the following electronegative gases: SF6, CF4, C2F6, C3F8, C4F10, CCl2F2, O2, air, H2O, CO2, F2, NF3, Cl2, Br2, I2, N2O, NO, HCl, NH3. Graphical presentations comparing measured and calculated data are given for the electron drift velocity, the ratio of diffusion to mobility, the electron attachment and ionization coefficients, and the electron growth constant as functions of E/N, the reduced field strength, for each gas. Graphs of the detachment and excitation coefficients are presented where these data are available. Data originally reported in terms of rate coefficients as functions of mean electron energy are graphically presented in that form. Recommendations concerning reliability are made.
