We test the pairwise adatom-adatom interaction sets for H/Ni(lll) computed by Muscat by using Monte Carlo techniques to determine the lattice gas phase diagrams they imply and then comparing with experiment. Although the correct ordered phase is reproduced and the maximum disordering temperature is approximately correct, there remain topological… (More)

situation, the intensity of the center of the half-order beams is proportional to the number of sites (or adatoms) squared. It is distinct from the situation discussed by L.D
