Abstract : A study was made of the effect of uncertainties in specific reaction rate constants on the over-all rate of electron density decay in a highly ionized atmosphere. A number of computer runs were made with various rate constants varied individually and in combinations. From this certain recommendations of the accuracy needed in the values of specific rate constants were made. Some specific recommendations found were that the dissociative recombination reaction rate constants for N2(+), O2(+) and NO(+) have to be known with the same accuracy as that desired in deionization calculations. This is also true of the charge transfer reaction between O2(-) and O. Other reaction rate constants for which the accuracy is nearly as important are three-body attachment to O2, the ion-ion recombinations of O2(+) and NO(+) with O2(-), and the associative detachment of O(-) with N2. The effect of inaccuracies in rate constants varied with conditions and a limited number of conditions were used. Thus the significance of the finding of the unimportance of inaccuracies in some rate constants is somewhat limited. (Author)
