Abstract
Xenon diffusion on a Pt(111) surface is modeled using a classical traj ectory simulation employing an accurate semi-empirical potential funct ion. Good agreement with experimental results suggests that this syste m may provide a good empirical test for Hamiltonian transport models. Analysis of the trajectory data indicates that long and correlated fli ghts are centrally important in the diffusion process, although anomal ous diffusion is not observed. Evidence is seen for the influence of l ow order periodic orbits in promoting long flights.
