摘要：

Chemisorption of hydrogen on a Ni(7 9 11) stepped surface was studied by LEED, AES, UPS and work function measurements. Atomic hydrogen is chemisorbed on this surface and causes a rearrangement of steps. Hydrogen molecules are found to be inactive for such an effect. It is concluded that the step rearrangement is induced by the incorporation of atomic hydrogen into the subsurface region through step sites. Structural models for the step-rearranged states produced by hydrogen chemisorption are discussed.
