Strong selectivity for populating a doublet of states at 10.75 MeV in ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ has been observed in the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$${(}^6$Li, d${)}^{13}$C reaction. The spectroscopic strength to other states is a factor 10 less than that observed at 10.75 MeV. Narrow peaks are observed also at 13.41 and 14.12 MeV. The ${(9/2\mathrm{}}^{+}$ state at 9.5 MeV is weakly populated here in contrast to ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$${(}^6$Li${,}^3$He${)}^{13}$C, where it and the 10.75 MeV states are both strongly excited. The large 10.75 MeV spectroscopic strength is not consistent with a 1p-shell origin for these states.
