Query: Anisotropic Pairing on a Three-Band Fermi Surface for $A_3{\rm C}_{60}$   We study a model for anisotropic singlet pairing in $A_3{\rm C}_{60}$, using
a realistic model for the Fermi surface in a hypothesized
orientationally-ordered doped crystal. Anisotropic solutions are studied by
combining numerical solutions to the gap equation in the low-temperature phase
with a Landau expansion near the mean field critical temperature. We focus on a
class of three-dimensional nodeless $d$-wave solutions to the model, which
exhibit a fully developed gap everywhere on the Fermi surface, but non-BCS
temperature dependence of the order parameter in the condensed state, a
relatively large value of the low-temperature gap, $2\Delta/kT_{\rm c}$ , and
non-BCS structure in the quasiparticle spectrum near the gap.
