The discharge was ignited between coaxial electrodes with a distance of 3.5 mm in a flowing mixture of 0.1-0.9 mmmol/s of CF3I and 0.5-6 mmol/s of buffer gas (Ar, He). The gas leaving the discharge was injected into the subsonic or supersonic flow of N2 and the concentration of generated atomic iodine and gas temperature were measured downstream (several cm) of the injection. The dissociation fraction calculated from the atomic iodine concentration was in the range of 7-30%. Due to a possible high rate of the atomic iodine loss by recombination after leaving the discharge, these values were considered as lower limits of those achieved in the discharge.
