A numerical renormalization group technique recently developed by one of us is used to analyse the Coulomb pseudopotential ($μ^*$) in $ C_60$ for a variety of bare potentials. We find a large reduction in $μ^*$ due to intraball screening alone, leading to an interesting non-monotonic dependence of $μ^*$ on the bare interaction strength. We find that $μ^*$ is positive for physically reasonable bare parameters, but small enough to make the electron-phonon coupling a viable mechanism for superconductivity in alkali-doped fullerides. We end with some open problems.
