Abstract
The initial ordered chemisorption stage of oxygen on Al(111) has been investigated using polarization-dependent surface extended x-ray absorption fine-structure measurements above the O absorption edge. The O-Al bond length in the threefold hollow adsorption site has been determined to be 1.79±0.05 Å. A strong polarization dependence of the extended x-ray absorption fine-structure signal allows the determination of the O-O distance (2.90±0.05 Å) between the chemisorbed oxygen atoms.
