Abstract
Results of a photoemission study of Sm on a Cu(100) single crystal surface are reported. From the binding energy of the Sm 4f levels it is concluded that the mixed valence of Sm on Cu(100) is of a heterogeneous nature. It is suggested that this conclusion also applies to Al(111) and Al(100).
