Electron swarm parameters in CF₃I and a set of electron collision cross sections for the CF₃I molecule

Electron swarm parameters (the electron drift velocity, the longitudinal diffusion coefficient, the ionization and attachment coefficients and the effective ionization coefficient) in pure CF 3 I were measured in the range of E / N over 140–1000 Td. These swarm parameters were analysed using a Boltzmann equation analysis, and a set of electron collision cross sections for the CF 3 I molecule was derived so that it was consistent with the measured electron swarm parameters in CF 3 I. The present set of electron collision cross sections of CF 3 I derived was used to calculate the limiting E / N values in CF 3 I–N 2 mixtures to confirm that the results of the calculation agreed well with the recent experimental results.
