Abstract
A complete set of polarised XAS spectra at Cu L3 and Bi L3- edges have been recorded on a well characterised single crystals of Bi2Sr2CaCu2O 8+ superconductor. The Cu L3 spectra shows an energy difference of 400 meV between z(3d3z2-r2) and x,y(3dx2-y2) components, with a significa nt intensity in E parallel-to c polarisation. The Bi L3-edges show cle arly the energy shift of superconductor spectra towards low energy wit h respect to Bi(III) references confirming again the Bi-O layers as el ectron reservoir.
