Abstract : Measurements of the magnitude and time dependence of X-ray induced absorption over Midway during the July 9, 1962, high-altitude nuclear explosion allowed us to infer bounds on the dissociative recombination coefficient alpha of the D-layer of the ionosphere. It is shown here that a daytime experiment would allow a unique determination of alpha. By combining the daytime data with the already available nighttime data, one could infer the in situ detachment rate of the daytime ionosphere. We find that a low-yield explosion (a few KT) is adequate for the purpose of the experiment. (Author)
