Abstract : High-altitude EMP source currents and ionization resulting from Compton scattering of gamma rays were evaluated on the basis of the forward-scattering of the Compton electrons. Large differences were noted between results of the most accurate approximation and the forward-scattering approximation for the case of relativistic Compton electrons, especially of late times. Accuracy at late times required a more accurate approximation than at early times. A special forward-scattering approximation was tested which should allow accurate evaluation of peak fields below the source region. (Author)
