Excitation functions for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$)${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ elastic and inelastic scattering have been measured in the energy range $23\le E_{\mathrm{c}.\mathrm{m}.\mathrm{}}\le 32$ MeV. Two strong structures at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=25.5\mathrm{} \mathrm{and} 29.6$ MeV are observed in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$($3^{-}$,6.13 MeV) exit channel; angular correlation measurements at these energies suggest spin assignments of ${15}^{-}$ and ${16}^{+}$, respectively.
