A careful measurement of the lattice parameters of pure Pb and a Pb+(0.0918 at.% Au) sample after a quench and equilibrium annealing cycle shows that Au in both monomer and "tetramer" defect states produces lattice contraction with the "tetramer" somewhat remarkably having the larger effect per atom. The observed monomer contraction suggests that the majority site occupancy for Au is substitutional and that the rapid Au diffusion must therefore involve a substitutional-interstitial mechanism.
