Proton-Proton Bremsstrahlung at 47 MeV

Abstract

The cross section for proton-proton bremsstrahlung at 47 MeV was measured by detecting the two protons at 30° on either side of the beam. Strongly noncoplanar events were not accepted. The integrated cross section and differential cross section as a function of $\gamma$-ray polar angle are in reasonable agreement with recent theoretical predictions. A survey of all presently available (30°, 30°) measurements and predictions is given.
