Angular correlations have been investigated in the ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$${(}^{16}$O,xy) reaction at 77 MeV. Using a ${}_{}{}^{31}{}_{}{}^{}\mathrm{P}$ intermediate mechanism to model the interaction, attempts have been made to predict the α${+\mathrm{}}^{12}$C angular correlations at 65, 77, and 87.4 MeV. The calculations reproduce the shape of the correlations fairly well. However, the predicted angular correlation peaks too far out in angle to reproduce the experimental data. Several possible explanations for the shifting of the peaks are discussed.
