Abstract

Results from the study of a highly overdoped (OD) [Formula presented] with a [Formula presented] using angle-resolved photoemission spectroscopy are presented. We observe a sharp peak in the spectra near ([Formula presented]) that persists well above [Formula presented], a nodal self-energy which approaches that seen for the Mo(110) surface state, and a more [Formula presented]-independent line shape at the Fermi surface than the lower-doped cuprates. This allows for a realistic comparison of the lifetime values to the experimental resistivity measurements. These observations point to the validity of the quasiparticle picture for the OD even in the normal state.
