Quasielastic yields have been measured for the ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$${+}^{208}$Pb reaction at $E_{\mathrm{lab}{(\mathrm{}}^{28}}$Si)=166 MeV. A coupled-channels analysis was performed on the elastic and inelastic scattering, resulting in a good description of all data except for the angular distribution associated with inelastic excitation of the $3^{\mathrm{-}}$ state in ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$. A large fraction of the total reaction cross section was found to be contained in quasielastic single-neutron and single-proton transfer. The one-nucleon transfer data were analyzed using the distorted-wave Born approximation with optical-model parameters deduced from the elastic scattering analysis, and spectroscopic factors taken from the literature. The magnitudes of the single-nucleon transfer cross sections are reproduced to within a factor of 1.6 or better.
