We investigated the electron?phonon coupling (EPC), in the vicinity of the Fermi level, for the surface-weighted states of Mo(112) from high resolution angle-resolved photoemission data taken parallel to the surface corrugation (i.e. «1̄1̄1»). The surface-weighted bandwidth may be discussed in terms of electron?electron interactions, electron impurity scattering and electron?phonon coupling and exhibits a mass enhancement factor γ = 0.42, within the Debye model, determined from the experimentally derived self-energy. Gold overlayers suppress the mass enhancement of the Mo(112) surface-weighted band crossing the Fermi level at 0.54 Å-1.
