The effective ionization coefficients in ultradilute SF{sub}6 + N{sub}2 gas mixtures are calculated from a Monte Carlo technique over the range 100 ≤ E/N ≤ 270 Td together with electron drift velocities and pulsed Townsend mean energies. SF{sub}6 contents in the mixtures of 0.1, 0.3, 0.5, 0.7, and 1 are considered. The effective ionization coefficients decrease with the increase of the SF{sub}6 concentration in the mixtures at a given E/N, while the variation of the drift velocities and pulsed Townsend mean energies with respect to SF{sub}6 concentrations is relatively constant in the E/N range of this paper.
