No evidence is found in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^{12}{}_{}{}^{}\mathrm{C},\alpha ){}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ reaction for a $6^{+}$ member of a "superband" predicted by Vogt to lie in the range $E_x=10\mathrm{}-11$ MeV. We suggest the $6^{+}$ state at 12.14 MeV as the $6^{+}$ member of the core-excited band built on the 7.20-MeV $0^{+}$ state.
