Abstract

Using an anisotropic hybridization matrix element, V(k\vec k), reflecting cubic symmetry at the ``rare-earth'' sites of the infinite U Anderson lattice, we calculate the bare quasiparticle scattering amplitude to order 1/N using slave Bosons and find significant differences with previous results under spherical symmetry. Due to exchange of density fluctuations, we find an instability. toward Eg_g and T1g_{1g} (even-parity) pairing.
