Query: Resonance Interaction Induced by Metal Surfaces Catalyses Atom Pair
  Breakage   We present the theory for retarded resonance interaction between two
identical atoms at arbitrary positions near a metal surface. The dipole-dipole
resonance interaction force that binds isotropically excited atom pairs
together in free space may turn repulsive close to an ideal (totally
reflecting) metal surface. On the other hand, close to an infinitely permeable
surface it may turn more attractive. We illustrate numerically how the
dipole-dipole resonance interaction between two oxygen atoms near a metal
surface may provide a repulsive energy of the same order of magnitude as the
ground-state binding energy of an oxygen molecule. As a complement we also
present results from density-functional theory.
