Abstract

We report ultrahigh-resolution angle-resolved photoemission results on kish graphite. We found an evidence for a sharp quasiparticle peak around K(H) point. Self-energy analysis of quasiparticle lifetime indicates presence of a strong electron-phonon coupling and the linear energy-dependence of scattering rate which shows marked deviation from the conventional Fermi-liquid theory.
