Measurements are reported of the electron drift velocity, w, in CHF3 gas and in its mixtures with argon. The E/N dependence of w in the mixtures exhibits regions of distinct negative differential conductivity. A small electron attachment rate constant (- 13 X 10-14 cm3 s-1 for density-reduced electric fields, E/N < 50 x 10-17 V cm2) has been measured, which may be due to impurities.
