From measurements of the electrical resistance of heavy-fermion CeCu/sub 6/ subjected to hydrostatic pressures, we infer a continuous pressure-induced transition from Kondo-lattice to more strongly mixed-valence behavior. The resistance is found to scale over an appreciable temperature interval with a pressure-dependent characteristic temperature that reflects this transition. Similarities in the resistive behaviors of CeCu/sub 6/ and CeAl/sub 3/ are discussed.
