摘要：

We have studied the polarization dependence of the Cu 2p absorption spectra in a (Bi0.84Pb0.16)2Sr2CaCu2O8 single crystal. At normal incidence (Exy plane) we found an intense peak at 932.0 eV, which becomes much weaker and shifts 500 meV toward lower energies at grazing incidence (Ezaxis). Also, at grazing incidence a structured absorption step appears starting at 935.8 eV. The interpretation of these results is discussed. © 1990 The American Physical Society.
