Proton induced γ-ray yields

To extend the information available for prompt nuclear analysis and to investigate discrepancies between published data, measurements were made of the γ-ray yields from proton induced nuclear reactions in F, Na, Mg, Al, Si, Cr, Mn, Fe, Cu and other elements. A large volume Ge(Li) detector was used with pure element or compound targets. Measurements were made at proton energies of 2.0 and 2.5 MeV. Thick target angular distributions are usually isotropic, but departures from isotropy can be observed when the yield is dominated by a large resonance near the incident energy. Integral calculations were made to obtain the stopping power correction factors necessary to derive pure element yields from measurements on compound and mixture targets. (orig.)
