Al Surface Relaxation Using Surface Extended X-Ray-Absorption Fine Structure. Bianconi, A. & Bachrach, R. Z. Phys. Rev. Lett., 42(2):104–108, 1979.
Al Surface Relaxation Using Surface Extended X-Ray-Absorption Fine Structure [link]Paper  doi  abstract   bibtex   
The surface extended x-ray-absorption fine structure (EXAFS) of a single crystal has been measured for the first time. By comparison with parameters obtained from bulk aluminum EXAFS, a decrease of the interatomic distance (\${\textbackslash}ensuremath{\textbackslash}Delta{\textbackslash}mathcalr=0.15ıfmmode{\textbackslash}pm{\textbackslash}else±{\textbackslash}fi0.05\$ \textbackslashAA) at the Al(111) surface has been found. No relaxation is found of the Al-Al separation on the (100) face.
