The angular distributions of the ground-state neutrons from the reaction ${\mathrm{B}}^{11}(d, n){\mathrm{C}}^{12}$ have been measured in the deuteron energy range of 0.500 to 1.15 Mev. A single stilbene crystal counter was employed as a neutron detector. At a bombarding energy of 0.8 Mev the neutron angular distribution exhibits a strong forward component, while at 1.15 Mev the distribution is more isotropic. The data are consistent with an analysis based on nuclear stripping theory.
