Abstract
The high energy gamma-rays arising from 140-Mev proton bombardment of several elements has been studied using a scintillation counter telescope to detect secondary electrons. The angular distribution is consistent with an approximately isotropic distribution in the center-of-mass system if we assume the bremsstrahlung to come from collisions inside the nucleus. This is in disagreement with a phenomenological potential treatment of the force or the scalar-meson theory.
The form of the spectrum is found to be consistent with the shape and the dependence on much as would be expected from an opaque nucleus with only the neutron contributing to the bremsstrahlung.
