Abstract

The photoprotons ejected by bremsstrahlung photons from nitrogen gas enriched in N15 were detected in nuclear emulsions and the proton energy and angular distributions measured for 18.7- and 24.6-Mev betatron energies. The photoproton yield is 105 protons per atomic weight per roentgen unit at 24.6 Mev. The integrated cross section in the giant resonance is 10-Mev millibarns for ground-state transitions. Structure is observed in the giant resonance and the angular distributions in this region are predominantly sin2θ.
