摘要：

The temperature dependence of the rate constant and the effective diffusion coefficient of incorporation of lead atoms from an underpotential monolayer adsorbate on Ag(111) into the silver crystal lattice at low and high coverages is investigated. The transfer activation energy in both cases and the lateral bond energy of the lead atoms in the adsorbate are determined. The resulting energy values compare favourably with those known from the literature.
