Abstract
The electronic structure of the high-T-c superconductor Sr2CuO2F2+delt a has been investigated by means of x-ray-emission spectroscopy(O K-al pha, Cu L(alpha,beta), F K-alpha), x-ray-photoelectron spectroscopy, a nd band-structure calculations using the full-potential linear muffin- tin orbital method. The local environment of the F atoms and the valen ce state of the Cu atoms in Sr2CuO2F2+delta are discussed. On the basi s of the x-ray-photoelectron and x-ray-emission spectra it is conclude d that the F atoms preferentially bond to Sr atoms in this compound.
