Embedded correlated wavefunction (ECW) theory is used to characterize the Kondo states formed by Co atoms adsorbed on Ag(111) and Ag(100). Clusters containing the adatom are described with CW theory, while effects of the extended crystal are included via an embedding potential. The predicted Co d-electronic structure, combined with earlier predictions for Co on Cu surfaces, explains the different tunneling behavior observed with the scanning tunneling microscope(STM) for Co adsorbed on different coinage metal surfaces.
