Van der Waals Potentials of 4 He Derived from Adsorption Isotherms
Van der Waals potentials for thin 4 He films on glass and on diamond are deduced from helium adsorption measurements. Significant deviations from the expected cubic dependence on the areal mass density are found. The commonly used values for glass appear to be much too small.
