摘要：

We report the electron swarm parameters, the drift velocity, and the ionization coefficients in CF3I gas for relatively wide ranges of reduced electric fields (E/N). The drift velocity is measured based on the arrival-time spectra of electrons for E/N=200-3000 Td, and the first and second ionization coefficients are determined by the steady-state Townsend method for E/N=400-5000 Td. The results are compared with those of CF4 to show that CF3I has a high reactivity for electron attachment in a low E/N region resulting in a much higher limiting E/N value (440 Td) than that of CF4.
