A discussion of long-range crystalline order, dimensionality, and diffusion suggests the reasons for solidlike heat capacities of helium monolayers having relatively low characteristic temperatures and large interatomic spacings.
We have obtained a thermodynamic state of thin helium films which permits precision measurements of their properties. Third-sound resonances indicate a transition in the superfluid density of these films. This transition is accompanied by an exponential rise in the thermal resistance of the...
We have made adsorption measurements of He4 on a copper sponge preplated with a series of noble-gas layers. The behavior of the isosteric heat of adsorption and the partial molar entropy of submonolayer He4 on these substrates is presented and discussed. The general behavior is of a rapid...
Wave functions and energies for band states of helium atoms in the two-dimensional periodic potential at the surface of a semiinfinite rare gas solid have been studied. In the case of Kr and Ar substrates, the atoms are highly localized and, correspondingly, the band widths are small. In a third...
