Angular correlations between deuterons and alphas in the reaction ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$${(}^{14}$N,d${)}^{24}$${\mathrm{MG}}^{\mathrm{*}}$(α${)}^{20}$Ne(g.s.) at beam energies of 30, 33, 36, and 42 MeV have been used to investigate the reaction mechanism. Evidence for possible ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ cluster transfer to the 13.45 MeV $6^{+}$ state in ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ is presented. The transfer of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$($2^{+}$) clusters seems to be the dominant process. In addition to the correlation measurements, deuteron angular distributions were measured at 33 and 42 MeV and an excitation function at a lab angle of 8° was obtained between 30 MeV and 45 MeV in 3 MeV steps. The angular correlations, deuteron angular distributions, and the excitation function were fitted using the finite range distorted wave Born approximation (FRDWBA) and the Hauser-Feshbach formalism of compound nucleus formation.
