The inclusion of the quadrupole moment of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ in coupled-channels calculations removes the need to renormalize the real double-folded potential, obtained from an effective nucleon-nucleon interaction, for ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$, ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ and ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$+${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ elastic scattering.
