New data on resonances in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ system are presented. A systematic pattern is observed suggesting that theoretical models which have recently been formulated for the mechanism of resonances appearing in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ system also apply to this system. Furthermore, energies, spins, and widths for entrance-channel resonances predicted by a recent microscopic calculation of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ scattering agree very well with the data presented here.
