Resonant inelastic X-ray scattering (RIXS) spectra at the Fe K-edge were measured for a single-crystal of the iron oxypnictide superconductor PrFeAsO0.7(Tc=42K). They disclose a weak, broad feature centered around 4.5 eV energy loss, which is slightly resonantly enhanced when the incident energy is tuned to the vicinity of the 4p white line. We tentatively ascribe it to the charge-transfer excitation between As 4p and Fe 3d.
