The adsorption and insion of hydrogen atom on Pd(997) step surface was studied by the pair-potential method. Calculated results show that the most stable adsorption state is one of the hydrogen atoms being adsorbed under the step. New vibration modes of the adsorption states were analyzed theoretically. 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.
