Abstract
Measurements of the temperature dependence of the dissociative recombination coefficients in and are reported under conditions in which . For both gases, the low-temperature variation of was found to have an exponent of , while at high temperatures the exponent was - 1.5 ± 0.1. The break between the high- and low-temperature dependencies, which occurred at 900° K for neon and at 670° K for argon, is seen to be a measure of the spacing between the ground and first vibrational levels in these molecular ions.
