Abstract
We analyze the line shape differences between Bi4Ca3Sr3Cu4O16+x Fermi-edge photoemission spectra taken at room temperature and at temperatures below Tc. A quasiparticle theoretical approach indicates that these changes can be interpreted, in first approximation, in terms of a displacement of the leading edge, reflecting the creation of a superconductivity gap of a few tens of millivolts.
