The Si(111)(root 3 x root 3)R30 degrees-Pb reconstruction has been studied
using medium-energy ion scattering. The ion scattering data were taken from
two different scattering geometries and compared with Monte Carlo simulati
ons of the scattering curves, varying different structural parameters syste
matically until a suitable match between experiment and theory was obtained
. A new structural model is proposed on the basis of these results.
