Query: Adsorption-induced constraint on delocalization of electron states in an
  Au chain on NiAl(110)   We have carried out a density functional study of the localized constraint on
the delocalized, unoccupied resonance states in a mono atomic Au chain on a
NiAl(110) surface by adsorption of a CO molecule on one of the adatoms in the
chain. This constraint was observed recently by scanning tunnelling microscopy
and spectroscopy. The repulsive interaction of the occupied 5${\sigma}$
molecular state with the unoccupied, resonance state in a Au adatom in the
chain is found to break the degeneracy of the Au adatom-induced resonance
states and to disrupt their delocalization in the chain.
