In this paper we review the recent advances of the He atom scattering experiments and the theoretical interpretation of the time-of-flight (TOF) spectra relative to clean flat metal surfaces in the one-phonon regime. We discuss the atom-surface scattering mechanism, including the anomalies in the metal surface phonon spectrum and the details of the atom-surface interaction potential. In particular we focus the discussion on the anticorrugating effects in the TOF intensities.

Abstract
In this paper we review the recent advances of the He atom scattering experiments and the theoretical interpretation of the time-of-flight (TOF) spectra relative to clean flat metal surfaces in the one-phonon regime. We discuss the atom-surface scattering mechanism, including the anomalies in the metal surface phonon spectrum and the details of the atom-surface interaction potential. In particular we focus the discussion on the anticorrugating effects in the TOF intensities.
