A model for crystal field triplet ground states of rare earth or actinide ions with dipolar and quadrupolar couplings to conduction electrons is studied for the first time with renormalization group methods. The quadrupolar coupling leads to a new nontrivial, non-Fermi-liquid fixed point, which survives in an intermediate valence Anderson model. The calculated magnetic susceptibility displays one parameter scaling, going as T-α (α ≈ 0.4) at intermediate temperatures, reminiscent of the non-Fermi-liquid alloy UCu5-xPdx.
