The angular distributions of the first excited state neutrons from the reaction ${\mathrm{B}}^{11}(d, n){\mathrm{C}}^{12}$ have been measured at deuteron bombarding energies of 0.6 and 1.0 Mev, using a single stilbene crystal counter. The distributions are asymmetric about the 90° direction, showing an excess in the forward direction. The data are consistent with an analysis based on nuclear stripping theory. Total cross sections were obtained at 0.6, 0.8, and 1.0 Mev.
