The (γ,p) reactions in fluorine and carbon were studied with bremsstrahlung X-rays of energies up to 24 MeV. Photoprotons were observed by using nuclear plates. Energy spectrum of photoprotons from fluorine exhibits peaks at 3.8, 4.6, and 7.4 MeV which are in good accord with those observed previously by Forkman and Wahlst1om, and Dodge and Barber. In addition to these we found peaks at 1.9 and 2.8 and a somewhat uncertain peak at 6.1 MeV. Angular distributions of photoprotons from fluorine showed an asymmetry around 90° with respect to the direction of incident photons, which suggests interference between absorbed photons of different parities. In the case of carbon, a main peak at proton energy of 6.0 MeV was observed along with slight humps at 4.5 and 5.2 MeV. The observed structure is in good agreement with those reported previously.
