| Popis: |
The monolayer of adsorbed xenon on the (1) surface of silver was studied using low- energy electron diffraction. The structure is an hexagonal lattice aligned with but out of registry with the substrate. The Xe-Xe spacing at 25 K is 4.44 ± 0.01 A in the full monolayer and 4.47 ± at less than full coverage. The Xe-Ag spacing is 3.5 ± 0.1 A. Here 〈u⊥〉2T, the meansquare vibrational amplitude normal to the surface divided by the temperature is (1.83 ± 0.4 × 10−4 A2/K. The heat of adsorption is 0.28 ± 0.03 eV/atom. |
