We have studied the electronic structures of ternary Ce compounds CePdX (X=As, Sb) by means of high resolution 4d-4f resonance photoemission spectroscopy. In the Ce 4f spectra, the relative intensity ratios between the well-and poorly-screened peaks are appreciably different between these materials, while the spectra in the vicinity of the Fermi level have similar features with two shoulders split by the spin-orbit splitting. We have analyzed the experimental line-shapes of the Ce 4f spectra with using the non-crossing approximation calculation within the Anderson impurity model. It is found that the spectral difference originates from the differences of the energy positions of the valence-band and the bare Ce 4f level as well as their mutual hybridization strength.
