Frequency-dependent conductivity measurements are reported in the dc to 150-GHz range in the moderately heavy-fermion compound CePd/sub 3/. A Drude expression is found with a renormalized relaxation time tau/sup */, and a renormalized plasma frequency ..omega../sub p//sup */ at low temperatures. This experiment represents the first direct measurement of these quantities, and the enhanced mass obtained from the frequency-dependent conductivity compares favorably with that determined from thermodynamic measurements.
