that due to the antiferromagnetic correlations in the host material, the hopping is expected to be reduced over the antiferromagnetic correlation length, of order a few lattice spacings.[@gabay] This renormalization might be expected to be more important in the case of Zn than Ni, due to the stronger bare potential.[@LLWang:2005] We therefore plot in Fig. \[fig6\](a,b) the resonance in a homogeneous background order parameter ($\delta\Delta=0$) for various values of the hopping near the impurity. It is seen that the reduced hopping dramatically suppresses the weight in the impurity resonance on both the impurity \[Fig. \[fig6\](a)\] and NN \[Fig. \[fig6\](b)\] sites, which is lost to the antibound state outside the band. The resonance position will shift somewhat, however, since the effective potential for the impurity which enters in the determinant of the $T$-matrix is changing. As shown in Fig. \[fig6\](c-f), assuming a sufficiently large renormalized hopping in large-gap regions, it is possible to completely wipe-out what would be a well-defined sharp resonance in a small-gap region. Thus, provided the experimental data are consistent with individual Zn’s displaying small shifts in the resonance position in intermediate strength gap patches, the conventional scenario reviewed in the section, modified by kinetic energy renormalization from
