The Ce 4f-derived states in CeRhX (X=Sn and In) were directly examined by means of high-resolution 3d-4f resonance photoemission spectroscopy. Compared with the Kondo metal CePtSn, which has a low Kondo temperature, CeRhX has a strong Ce 4f $^{1}$ weight near the Fermi level ( $_{rm F}$ ) and has a weak Ce 4f $^{0}$ peak, indicating a strong valence fluctuation. The Ce 4f $^{1}$ spectral features indicate that the c-f hybridization strength in CeRhSn is weaker than that in CeRhIn.
