Abstract
The total neutron yield of the reaction has been measured in the alpha-particle bombarding-energy range of 2.5 to 5.1 MeV. Six new anomalies were observed in the yield curve at alpha-particle energies of 4.030±0.015, 4.07±0.04, 4.17±0.04, 4.434±0.010, 4.70±0.04, and 5.004±0.010 MeV. These would correspond to excitation energies in the compound nucleus of 9.361, 9.39, 9.47, 9.675, 9.88, and 10.119 MeV. The experimental widths vary from 21 to 200 keV. An approximate value of the average alpha-particle strength function was obtained.
