摘要：

The role of adsorbate interactions in clustering and effecting appreciable changes in activation energy (DELTA-E) is shown to be significant even at T > T(c). Using a modified mean-field approach, we show that if a correction to ground-state probability is invoked along with DELTA-E, then attractive and repulsive forces predict enhancement and decrease in surface rates, which is an unconventional result.
