Cross Sections of Gamma-Proton Reactions

Abstract
Using the University of Pennsylvania betatron, the energy dependences of the γp cross sections of C, Al, Co, Ni, and Cb have been measured. The cross-section curves exhibit the resonance character found in γn reactions. The significant parameters of each of the curves are tabulated. From the data of this paper and the known γn cross-section data, the sum of neutron and proton integrated cross sections is evaluated for carbon and nickel.
