Abstract
SEXAFS of the low temperature Na 4 x 4 structure formed on Al(111) has been analysed using a least squares optimisation program. Without anh armonicity a rotated cluster model with a bond distance of 3.70 +/- 0. 4 Angstrom and an unrotated cluster give good agreement. Including an anharmonic contribution the close packed model, with Na-Na bond length of 3.81 Angstrom is also a possible candidate. In all cases the neare st neighbour bond length is 2.65 +/- 0.08 Angstrom.
