Abstract
The through-bond interaction of two H atoms on (100) tungsten has been calculated in a surface molecule approximation using both Anderson's and Hubbard's hamiltonians, and assuming a linear WzH local geometry for chemisorbed hydrogen. There is a short range repulsion preventing two such adsorbed H atoms from occupying adjacent sites amounting to 0.020 Ryd for Anderson's model, and 0.010 Ryd for that of Hubbard.Keywords
