We report the use of the techniques of scanning tunneling microscopy and impact-collision ion scattering spectrometry to study the in-plane geometry of both the (root)3X(root)3 and 2(root)3X2(root)3 reconstructions of Sn on Si(111). For the (root)3X(root)3 reconstruction, the Sn adatoms were found to prefer fourfold atop (T4) sites. For the 2(root)3X2(root)3 reconstruction, a two-layer epitaxial Sn model with a four-atom unit cell on the top layer is found to provide the best agreement with experimental data.
