The angular and energy distributions of alpha particles resulting frora Co/sup 59/(n, alpha )Mn/sup 56/ and Mn/sup 55/(n, alpha )V/sup 52/ reac tions induced by 14.8-Mev neutrons were raeasured with Ilford C2 nuclear plates. As in the case of Al/sup 27/(n, alpha )Na/sup 24/ reaction, the angular distributions for the entire energy region are approximately 90 deg symmetrical and concave upward, and the energy distributions show that the alpha particles with energies below the Couloumb barrier are raore emitted than has been expected. The curves on a semilog plot of the relative level density calculated from the energy distributions of the alpha particles cannot fit a straight line. The total (n, alpha ) cross sections of cohalt end manganese are 84 mb plus or minus 15% and 96 mb plus or minus 15%, respectively. The results are compared with the predictions of the statistical theory of nuclear reactions. (auth)
