Abstract
The transformation of the (1 x 2) Rh (110) missing row non-equilibrium structure to the stable (1 x 1) structure has been studied by He atom scattering. The transformation is found to take place by the formatio n of islands of the (1 x 1) phase which are elongated in the [11BAR0] direction giving rise to a mesh of alternately up and down steps. A nu merical simulation, based on an anisotropic classical 2D Ising model, is presented and shows that the experimental data can be interpreted a s a spinodal decomposition of a lattice gas.
