The cross section for the reaction N/sup 15/(p, gamma /sub 0/) at proton energies below 700 kev was measured. The results fit well an analysis in terms of two interfering 1/sup -/ resonances at 338 and 1010 kev (12.43 Mev and 13.09 Mev respectively in O/sup 16*), with destructive inteference in the energy region between the resonances. The N/sup 15/ (p, alpha /sub 0/) cross section was analyzed using the same parameters, with constructive interference between the resonances, and a good fit to the experimental cross section is obtained. The values of S obtained by extrapolation to a proton energy of 25 kev (laboratory system) are 32 kev-barn and 7.2 x 10/sup 4/ kev-barn respectively for the N/sup 15/(p, gamma /sup 0/) and N/sup 15/(p, alpha /sub 0/) reactio ns. The angular distributions of the N/sup 15/(p, alpha /sub 0/) reaction were analyzed. The presence of a 0/sup +/ resonance near 500-kev proton energy, and a 2/sup +/ resonance near 1000-kev proton energy, is indicated. (auth)
