      abstract     = {When surface-state electrons scatter at perturbations, such
                      as magnetic or nonmagnetic adatoms or clusters on surfaces,
                      an electronic resonance, localized at the adatom site, can
                      develop below the bottom of the surface-state band for both
                      spin channels. In the case of adatoms, these states have
                      been found very recently in scanning tunneling spectroscopy
                      experiments for the Cu(111) and Ag(111) surfaces. Motivated
                      by these experiments, we carried out a systematic
                      theoretical investigation of the electronic structure of
                      these surface states in the presence of magnetic and
                      nonmagnetic atoms on Cu(111). We found that Ca and all 3d
                      adatoms lead to a split-off state at the bottom of the
                      surface band which is, however, not seen for the sp elements
                      Ga and Ge. The situation is completely reversed if the
                      impurities are embedded in the surface: Ga and Ge are able
                      to produce a split-off state whereas the 3d impurities are
                      not. The resonance arises from the s state of the impurities
                      and is explained in terms of strength and the interaction
                      nature (attraction or repulsion) of the perturbing
                      potential.},
