Nonpeculiar Behavior of the (O16,C12) Transfer Reaction in thes−dShell

Recent analyses of (${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$) four-nucleon transfer data in the $s-d$ shell have suggested (a) that the transfer occurs with the $\alpha$ cluster in its 28.5-MeV excited state, and separately (b) that weakly absorbing optical potentials must be used. Our analysis of four-nucleon transfers measured in the reaction ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$)${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ contradicts such peculiar features in the (${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$) reaction, and yields spectroscopic information in agreement with theoretical predictions.
