An oscillation similar to that in extended x-ray absorption fine-structure (EXAFS) measurements was observed in the x-ray Raman spectra of graphite by exciting 8265-eV x rays from synchrotron radiation. From an analysis employing the formula used for EXAFS, the carbon-carbon interatomic distances are obtained which are in good agreement with the known values in graphite. Thus, x-ray Raman scattering by hard x rays is a very promising method for the determination of the local structure around light elements.
