摘要：

Electron swarm parameters (the electron drift velocity, the longitudinal diffusion coefficient, the ionization and attachment coefficients and the effective ionization coefficient) in pure CF3I 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 CF3I molecule was derived so that it was consistent with the measured electron swarm parameters in CF3I. The present set of electron collision cross sections of CF3I derived was used to calculate the limiting E/N values in CF3I-N-2 mixtures to confirm that the results of the calculation agreed well with the recent experimental results.
