The Ce 4f-derived states in CeRhX (X{double bond, short}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 4f1 weight near the Fermi level (EF) and has a weak Ce 4f0 peak, indicating a strong valence fluctuation. The Ce 4f1 spectral features indicate that the c-f hybridization strength in CeRhSn is weaker than that in CeRhIn
