Double-folding model potentials generated from a realistic nucleon-nucleon interaction and densities that are consistent with electron scattering are used to generate angular distributions for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ elastic scattering at 99 MeV. When used to calculate observed angular distributions it is found that the double-folding model potential is roughly twice the potential required to generate a fit to the data. This is consistent with observations at both lower and higher ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ energies.
