The ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^{12}{}_{}{}^{}\mathrm{C}, \alpha ){}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ reaction has been studied at bombarding energies of 36.0, 36.5, and 37.0 MeV. States up to 16 MeV excitation in ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ were identified. Several previously unreported levels were observed, a number of which are excellent candidates for missing unnatural-parity states. We summarize existing spin-parity information for several "elusive" states.

NUCLEAR REACTIONS ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^{12}{}_{}{}^{}\mathrm{C}, \alpha )$, $E_{{}_{}{}^{12}{}_{}{}^{}C}=36.0, 36.5, 37.0$ MeV, enriched target, measured $\sigma \left(\theta \right)$; deduced ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ levels.
