Abstract
BRANSCOMB has provided further results in support of a figure of about 1.465 eV. for the first electron affinity of atomic oxygen E(O → O−), and there is strong evidence for this value. However, the difference between this result and the value of Metlay and Kimball1, E(O → O−) = 2.33 eV., obtained from electron attachment at a hot filament, still has to be accounted for. In addition, various extrapolation methods2 give rather lower values than 1.465 eV. for the first electron affinity of oxygen. For example, the extrapolation procedure used by us yielded E(O → O−) = 1.044 eV., and it seems appropriate to make some comments on this procedure.
