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 $p-n$ collisions inside the nucleus. This is in disagreement with a phenomenological potential treatment of the $p-n$ force or the scalar-meson theory. The form of the spectrum is found to be consistent with the $$\frac{dv}{v}$$ shape and the dependence on $$Z$$ much as would be expected from an opaque nucleus with only the neutron contributing to the bremsstrahlung.
