Abstract
An X-ray photoelectron spectroscopy study of Na-doped Bi-2212 cuprates is reported. Core level photoemission spectra were collected, at diff erent take-off angles, from a monophasic crystal. The results of the l ineshape analysis and the dependence of the core line intensity on the analyser take-off angle allowed us to rule out the presence of Na wit hin the Bi-O layers, indicating that Na+ is very likely replacing Ca2 or Si2+ ions.
