Abstract
From experimental determinations of the rate constants for the reaction , an activation energy, Ea=0.067 eV, was calculated. At 77°K, no contribution from this reaction was found in the afterglow of a pulsed discharge in helium; rather at 77°K the decay was found to be second order with a reaction constant about 2×10−9 cm3 atom−1·sec−1.
