It is very difficult to determine surface structures,

because of the low volume of the surfaces

Still: large number of observations

!

He I photoelectron spectra F = workfunction

B = Cs 5p3/2/5pl/2 for caesium and atoms between clusters;

B' = Rb 4p3/2/4pl/2 for Rb and atoms between clusters;

N

VV, OmVV = Auger peaks;

structures in the dotted curves: conduction band (CB)
