Electron Capture by Protons Passing Through Hydrogen

Abstract

Computational errors in a previous paper on this subject by one of us (TP) have been rectified. The recomputed capture cross sections agree fairly well with experimental data over the entire energy range from 50 to 1000 keV. In the original paper the disagreement was at energies above 150 keV, in spite of the fact that the approximation scheme adopted was expected to be better at higher than at lower energies.
