Abstract

The interaction potential for H₂ interacting with the (001) MgO surface has been constructed using effective medium theory (EMT). We have then calculated the band structure of a H₂ molecule moving in the laterally modulated molecule-surface potential, the isosteric, and specific heats. The calculated quantities have also been compared with recent thermodynamic measurements of H₂ on MgO powders. In addition, the specular scattering intensity has been calculated as a function of incident polar angle along the high symmetry directions.
