Proton-carbon bremsstrahlung calculation

Abstract
The Feshbach-Yennie approximation is applied to calculate the proton-carbon bremsstrahlung cross sections near the resonance at 1.7 MeV. In all but one case, the predicted cross sections are in very good agreement with the experimental data. The calculation includes not only the principal term of the approximation but also the correction term, which is negligible at an energy far from the resonance but becomes very significant in the region of the resonance.
