We have performed an angle-resolved photoemission study of overdoped La1.78Sr0.22CuO4, and have observed sharp nodal quasiparticle peaks in the second Brillouin zone that are comparable to data from Bi2Sr2CaCu2O8+δ. 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 (π,0), where the band is predicted to lie above EF.
