摘要：
Polarized-x-ray OK-alpha and CuL-alpha spectra of the high-T(c) superconducting YBa2Cu3O7-delta compound are presented. They show strong anisotropic features. The possible location of the holes, which are thought to be responsible for the superconducting properties, are discussed in the light of these experimental spectra. It seems that the CuO2 and BaO planes are important layers for these oxygenlike holes. Because of charge transfer and correlation effects, characteristic spectral features are obtained.
