Abstract
We use the variational theorem to evaluate the domain of parameter space such thatsome film exists on a given surface. This is accomplished by determining the binding energy variationally for a monolayer film at T=0. The He results are for the most part consistent with those of Cheng, et al., for the domain of wetting films. New results for H2 are compared with calculated parameters of noble gas adsorption potentials.

Values of D(C3) for H2 interactions with4He, Ne Ar, Kr and Xe are 20(305), 79 (996), 130 (1710), 145 (2000) and 150 (2280) K(Kå3), respectively.
The noble gas substrate parameters inserted in Ref. 8 are go −1=1+x−1 and Es=Ea(1+x)1/2, with x=2πnα and α=polarizability.
