The $J^{\pi }=6^{+} \mathrm{and} 7^{+}$ members of the $K^{\pi }=1^{+}$, 4p-2h rotational band in ${}_{}{}^{18}{}_{}{}^{}\mathrm{F}$ are identified at $E_x=9.472\mathrm{}\pm 0.010$ MeV and $E_x=11.074\mathrm{}\pm 0.020$ MeV on the basis of their selective population in the ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}({}_{}{}^7{}_{}{}^{}\mathrm{Li}, t){}_{}{}^{18}{}_{}{}^{}\mathrm{F}$ reaction, on the basis of their measured excitation energies, and on the basis of comparisons between the angular distributions of these triton groups and the angular distributions of the triton groups corresponding to other members of this band.
