The adsorption characteristics of adsorption geometry, binding energy, eigenvalue vibration and so on, and diffusion potential energy surface structures between atomic hydrogen and three low index planes of metal Cu have been systematically studied by means of 5-parameter Morse potential. Calculations reveal that only pseudo threefold hollow site and long bridge site without short-bridge site of hydrogen atom on Cu(110) appear under the conditions of low temperature and low coverage, which are supported by experiments and theories.

Key words: 5-parameter Morse potential, adsorption and diffusion, interactions of hydrogeN2copper, potential energy surface structure
