Partial‐fluorescence‐yield (PFY) x‐ray absorption measurements, using the optimized window widths of position sensitive detectors in wave‐length dispersive x‐ray spectrometers, have been applied for radiative‐process‐resolved (RPR) x‐ray absorption spectroscopy. We have measured PFY‐absorption spectra of graphite and diamond at the C K threshold and of h ‐BN and c ‐BN at the B K threshold. Resonant elastic x‐ray scattering was observed in graphite and h ‐BN on their PFY‐absorption spectra, and excitonic x‐ray scattering was observed in diamond and c ‐BN. These results show that PFY‐absorption measurements for RPR x‐ray absorption spectroscopy can provide the information about the electronic structures and the radiative‐decay process in inner‐shell excitation.
