Title: Soft-x-ray photoemission study of the electronic structure of Bi/sub 4/Ca/sub 3/Sr/sub 3/Cu/sub 4/O/sub 16+//sub x/

Abstract

We investigated the electronic structure of the high-temperature superconductor Bi/sub 4/Ca/sub 3/Sr/sub 3/Cu/sub 4/O/sub 16+//sub x/ with synchrotron-radiation photoemission spectroscopy. This study complements recent experiments focused on the Fermi-edge region, which discovered substantial line-shape changes related to the onset of superconductivity. In the present case, spectra taken at different photon energies exhibit a variety of features related to core and valence electrons. In particular, we exploit the photon energy tunability of the source to identify the valence Cu satellite with resonant photoemission.
