A study of the ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}({}_{}{}^3{}_{}{}^{}\mathrm{He},d){}_{}{}^{11}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^3{}_{}{}^{}\mathrm{He},\alpha ){}_{}{}^{11}{}_{}{}^{}\mathrm{C}$ reactions leading to the 8.11-MeV state in ${}_{}{}^{11}{}_{}{}^{}\mathrm{C}$ yields an unambiguous assignment of $J^{\pi }={\frac{3}{2}}^{-}$ for that state.
