Abstract
The oxidation of Al(111) has been studied with a wide range of experim ental and theoretical tools. Despite this attention it has only been w ith the use of MEIS that it has been possible to establish that at oxy gen exposures of up to 100 L there is no detectable subsurface oxygen. The oxygen concentration increases smoothly with exposure up to 200 L and furthermore it has been found that oxidation induces an enhanced aluminium atom yield in the surface peak. The location of the surface adsorption site was not possible with normal methods of blocking and s hadowing, however the site has been determined with the use of an ener gy-modulation method. This has identified the most probable site to be a C site.
