Abstract
The diffusion barrier for Pd/Pd(100) is determined via LEED experiment s independently from: (i) the onset of temperature variation of the Br agg intensity in both deposition and annealing experiments; and (ii) c omparison of experimental and model values for the ring diameter of th e diffuse diffraction profile at a single higher temperature in the nu cleation-and-growth regime. A value of 12-14 kcal/mol is consistently obtained.
