Anisotropic singlet state superconductivity is predicted for UIr/sub 3/ (an itinerant non-heavy fermion intermetallic) as was done earlier for UPt/sub 3/ (perhaps the prototype heavy fermion system). In both, this arises from strong Uf-Xd hybridization which yields a highly anisotropic Fermi surface (now confirmed by dHvA experiments of Taillefer et al. on UPt/sub 3/), electron - phonon interaction, and superconducting energy gap.
