The mechanism of the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^6{}_{}{}^{}\mathrm{Li},d){}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ reaction has been studied in the energy range $E_{{}_{}{}^6{}_{}{}^{}\mathrm{Li}}=19-24\mathrm{}$ MeV. For the states at $E_x=6.92\mathrm{} \mathrm{and} 7.12$ MeV we have (a) measured excitation functions in 200-keV steps where the deuterons were detected at 0°, and (b) measured $d-\gamma$ angular correlations at three bombarding energies where the deuterons were also detected at 0°. The excitation curves are found to be relatively smooth functions of bombarding energy. The angular correlations are similar at all three bombarding energies. The results of the angular-correlation measurements are compared with the predictions of both an $\alpha$-transfer mechanism (using the distorted-wave Born approximation) and a compound-nucleus mechanism (using the Hauser-Feshbach theory). The observed correlations are not completely consistent with the predictions of either theory. Angular correlations measured at lower energies were found to show strong changes with bombarding energy.
