Abstract

The adsorption and vibration of a hydrogen atom on the Ni(510) stepped surface was studied by pair potential method. Calculation results are in agreement with the experimental results. The adsorption and diffusion of a hydrogen atom on the Ni(997) stepped surface was also studied. By the anal. theor., the role of step is that the trapping potential wells are formed for the diffusion of a hydrogen atom on the lower terrace and the reflective potential is set up for that on the upper terrace, which also give support to experimental results satisfactorily.

Key words: NICKEL, HYDROGEN, ADSORPTION, VIBRATION, SURFACE DIFFUSION
