摘要：
The kinetics for the non-dissociative adsorption of gas phase molecules on a spatially homogeneous square lattice was simulated using a Monte Carlo method which accounts for the existence of an extrinsic precursor state. We find the sticking coefficients obtained using our simulations to be lower than those calculated using the equation derived by Kisluik, and show that islanding of the adsorbates on the surface and site revisiting in the precursor state account for the observed discrepancies.
