Nature of the ns-derived states for an isolated alkali atom on a surface

• It has recently been shown (for K/graphite) that experimental core level spectroscopy data for adsorbed Ar combined with calculations is a most valuable tool in order to obtain information about the alkali-derived unoccupied density-of-states [A. Sandell
