N2 - Electronic structures of CePdX (X = As, Sb) have been studied by x-ray photoemission, inverse photoemission and high resolution resonance photoemission spectroscopy. Analysis of the Ce 3d XPS spectrum of CePdAs by an Anderson impurity model, suggests that the Ce 4f electron number is very close to 1.0. In the Ce 4d-4f resonance valence-band spectra, strong two peaks derived from the bonding and anti-bonding states have been observed. The relative intensity ratios are different for CePdAs and CePdSb. Near the Fermi level, two additional shoulder structures split by the tail of Kondo resonance and its spin-orbit splitting partner have been found for both compounds.
