Abstract

We have performed an angle-resolved photoemission study of overdoped (formula presented) and have observed sharp nodal quasiparticle peaks in the second Brillouin zone that are comparable to data from (formula presented) The data analysis using energy distribution curves, momentum distribution curves, and intensity maps all show evidence of an electronlike Fermi surface, which is well explained by band-structure calculations. Evidence for many-body effects are also found in the substantial spectral weight remaining below the Fermi level around (formula presented) where the band is predicted to lie above (formula presented)
