High-resolution core-level spectra from the 
-Ag
surface considered as a standard in surface science have been obtained at
100 K. The sharp Si 2p spectra comprise three asymmetric surface-shifted
components, pointing to a metallic character of the surface. The strong S1
component due to the Si first layer atoms bonded to the adsorbed Ag atoms
is shifted 
to higher binding energy. This challenges the theoretical
prediction of a large charge transfer from the Ag atoms to this top Si layer
and points to the importance of final-state effects in the interpretation
of the Si 2p spectra.
