A numerical renormalization-group technique recently developed by one of us is used to analyze the Coulomb pseudopotential (${\mathrm{\ensuremath{\mu}}}^{\mathrm{*}}$) in ${\mathrm{C}}_{60}$ for a variety of short-range bare potentials. We find a large reduction in ${\mathrm{\ensuremath{\mu}}}^{\mathrm{*}}$ due to intraball screening alone, leading to an interesting nonmonotonic dependence of ${\mathrm{\ensuremath{\mu}}}^{\mathrm{*}}$ on the bare …
