A program of theoretical research on the structures and                         thermodynamics of thin physically adsorbed layers is described.                 The main goal is to achieve a quantitative understanding of a few               adsorbate/substrate combinations in which recent experimental                   data show effects of the competing spatial periodicity of an                    adlayer lattice and the substrate lattice.  Several topics are                  described which could lead to improved specification of the                     energy barriers to lateral motion of adsorbed atoms on the                      substrate surface.  The substrates considered are the (111) face                of platinum, the basal plane surface of graphite and the (001)                  face of magnesium oxide.  The adsorbates include xenon, krypton                 and molecular hydrogen and nitrogen.  The calculations include                  variational quantum mechanics for the ground state of hydrogen                  and deuterium and lattice dynamics and cell model approximations                for the near classical adsorbates.  The proposed work relies                    heavily on experimental data obtained from refinements of low                   energy electron diffraction, x-ray diffraction, thermal neutron                 scattering, and thermal helium atom scattering.
