Resonant inelastic X-ray scattering (RIXS) spectra at the Fe K-edge were measured for a single-crystal of the iron oxypnictide superconductor PrFeAsO $_{0.7}$ ( $T_{rm C}$ = 42 K). 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 white line. We tentatively ascribe it to the charge-transfer excitation between As and Fe .
