On the grounds of adsorption‐desorption equilibrium measurements (ADE), by means of massspectrometer techniques (MS), a family Ag/W adsorption isotherms was obtained. The isotherms were analysed on the basis of a simple model, which allowed to reduce the well known equations of two‐dimensional (2D) state to an Arrhenius form, which was finally used to investigate the energetics of Ag–W and Ag–Ag interactions. The presence of real attractive Ag–Ag lateral interactions was established. The lateral binding energy per bond was estimated to be ∼ 0.065–0.088 eV/atom and ∼ 0.152 eV/atom for the first and second monolayers (ML), respectively.
