($\gamma -n$) angular correlations are reported for the ${\mathrm{B}}^{11}(d, n){{\mathrm{C}}^{12*}}_{4.43}$ reaction at incident deuteron energies of 1 MeV and 0.7 MeV. Correlations were measured with the $\gamma$ detector perpendicular to the reaction plane and with the detector in the reaction plane. The latter were taken with the neutron detector at 0°, 10°, 45°, 90°, 135°, and 150°. Strong $P_4$ terms appear in the reaction plane corrections. This suggests either (1) the presence of compound nuclear effects in the reaction, or (2) a more complicated stripping situation than has previously been assumed for this reaction.
