The angular distributions of the reactions Ni/sup 58/(p, alpha )Co/sup 55/, o the ground and several excited states of the residual nuclei were measured at 12.6 to 14.25 Mev, at 10.02 to 14.43 Mev, and at 11.0 Mev, respectively, making use of solid-state detectors. Levels were found in Co/sup 55/ at 1.8 plus or minus 0.2, 2.2 plus or minus 0.2, and 2.45 plus or minus 0.2 Mev and in Co/sup 57/ at 1.77 plus or minus 0.02, 2.08 plus or minus 0.03. and 2.21 plus or minus 0.03 Mev. It was found that at about 14 Mev the forward peaks are predominant in the angular distributions for the reactions Ni/sup 58/ (p, alpha )Co/sup 55/ and Ni/sup 60/(p, alpha )Co/sup 57/ leading t o the ground states of the residual nuclei. The forward peaking disappears gradually with decreasing proton energy. The angular distributions of the reactions Ni/sup 58/(p, alpha )Co/sup 55/ and the residual nuclei have approximately 90 deg symmetry. The angular distributions of the reaction Ni/sup 58/(p, alpha )Co/sup 55/ leading to the ground state of Co/sup 55/ were measured at 28 energies between 8.96 and 10.32 Mev. Sharp variation of the shape of the angular distribution with the bombarding energy was obtained. The results of the measurements were analyzed with the theory of the compound nucleus developed by Ericson. (auth)
