摘要：

We present a systematic photoemission study of the influence of a one-monolayer rare gas coverage on the Shockley-type surface state on Ag(111) and Cu(111) surfaces. Depending on the rare gas-we used Ar, Kr and Xe as adsorbates-the surface state shows a characteristic,shift. towards the Fermi energy, whereas the spectral line-shape and the effective mass remain unchanged within the experimental uncertainties (energy resolution DeltaE approximate to 3.5 meV).
