The picture which emerges from our work and from the comparison with the available experimental information is that on the “open” surfaces like the bcc (001) the noble metal atoms are adsorbed in a regular 1 X 1 structure and their electronic structure is some intermediate betweeen the free atom and the bulk. At higher coverages the behaviour changes and structural modifications occur, which change the electronic structure.
