Thin films of Cs, quench condensed onto a He cold quartz plate, possess
electronic mean free paths which considerably exceed the film thicknesses.
When theses films are covered in situ with sub monolayers of Au, Ag,
In, Rh and Pb in the range between 0.01 and 1 monolayers the film resistance
and the Hall constant increase dramatically. This corresponds to a
scattering cross section of the surface impurities which is larger than 1 in
units of 
Various models are explored to explain these
unusual behavior. None yields a satisfactory explanation for this extremely
strong effect of surface impurities on the resistance and the Hall effect.
