Polarized neutron scattering techniques have been used to obtain information regarding the ground-state electronic properties of the intermediate-valence compound CePd/sub 3/. The spatial distribution of the magnetization induced by a magnetic field of 42.5 kG in a single crystal of CePd/sub 3/ has been studied at 100 and 4.2/sup 0/K. We find that at 100/sup 0/K the measured form factor is in good agreement with the free-ion 4f magnetic form factor of Ce/sup 3 +/. At 4.2/sup 0/K on the other hand, deviations from a 4f magnetic form factor were observed. An adequate fit to the experimental data taken at 4.2/sup 0/K can be obtained by assuming that the induced magnetization contains a significant component (approx. 17% of the total) of Ce-5d electronic character.
