Abstract

We calculate the shift in wetting temperature TW of a He film on a layered substrate. The latter consists of an alkali metal layer film of thickness d, deposited on a semi-infinite medium. TW can change from nonzero to zero (Cs) or vice versa (Na) as d changes. The shift is an extremely sensitive probe of long range van der Waals potentials.
