    Abstract

    The different peaks in the O K -edge near-edge fine structure of Y Ba2 Cu3 O7-x are interpreted here by using overlap population diagram. This study identifies the peaks in the spectrum as follows: (1) the first peak purely originates from O-Cu interactions, (2) the contributions from Y, Ba, and Cu are comparable at the second and third peaks, (3) and the fourth peak has the largest O-Cu interactions. Therefore, the first and/or fourth peaks and second and/or third peaks can be sensitive to the changes in the atomic and electronic structure at Cu and Y Ba sites, respectively. The spectral differences depending on the atomic site are also discussed.
