A continuum shell-model calculation of the $E2\mathrm{}$ strength in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ is presented in which an $E2\mathrm{}$ resonance at ∼ 27 MeV excitation energy is predicted. The results are consistent with experimental data on photoproton angular distributions and polarizations.
