Schematic of the FALP apparatus used in this experiment.
Relative ion abundances 10.7 ms after addition of 1.8 × 1010 cm−3 CF2Br2 to the afterglow at 300 K and 3 Torr. Solid lines are calculated best fits at k MN = 3 × 10−8 cm3 s−1; dashed lines are representative fits at the uncertainty limits of ±7 × 10−9 cm3 s−1.
Measured MN rate constants (points) of Ar+ with the indicated anions as a function of number density at 300 K. Black lines are previously reported rate constants (see references in text) measured at 300 K and 1 Torr. Thicker red lines are fits to rate constants for the indicated reactions as reported in Ref. 2 .
