We have performed an angle-resolved photoemission study of overdoped La_1.78Sr_0.22CuO₄, and have observed sharp nodal quasiparticle peaks in the second Brillouin zone that are comparable to data from Bi₂Sr₂CaCu₂O_8+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 E_F.
