Abstract
Generalized valence-bond calculations suggest that atomic oxygen chemisorbed on Ni(100) leads to two distinct low-lying states: (1) the radical state with Å and meV and (2) the surface oxide state with Å and meV. We suggest that the radical state dominates for and that the oxide state dominates for . We find that atomic H, Cl, and S lead to only one low-lying state.
