摘要：
Oxygen K edge and iron L(2,3) edge x-ray absorption spectra of SmFeO3 have been measured and theoretical analysis of these data on the basis of full multiple-scattering formalism in real space has been made. Combined oxygen K edge and Fe L(3) edge XANES is shown to be a useful tool for the study of RE orthoferrite electronic structure. The full multiple-scattering approach is found to be successful in analysing experimental oxygen K edge XANES in SmFeO3, while the single-scattering approximation is not valid in this case. Unoccupied oxygen p states interact with Fe 3d in a specific resonance manner.
