TL;DR: In this article, the accumulated spectra above 20 Mev, after subtraction of some e (as Fe/sup 59 /sup 0/ photon contamination, are assumed to be due to proton bremsstrahlung.
Abstract: Various targets were bombarded with 38 to 185-Mev protons. Photons from these targets were viewed at experimentally available angles from the proton beam with a 180-deg pair spectrometer capable of detection in the photon energy range of 8 to 150 Mev. The accumulated spectra above 20 Mev, after subtraction of some e (as Fe/sup 59 /sup 0/ photon contamination, are assumed to be due to proton bremsstrahlung. The general spectral features are explained in terms of electric- dipole radiation from p-n coilisions, where the target neutrons are in motion. The detailed features are discussed in terms of the available theoretical predictions; there is good agreement with the phenomenological calculation using n-p scattering data. (auth)
