  The Cu substitution by Zn and Ni impurities and its influence on the mass
renormalization effects in angle resolved photoelectron spectra (ARPES) of
Bi-2212 is addressed. We show that the nonmagnetic Zn atoms have much stronger
effect both in nodal and antinodal parts of the Brillouin zone than magnetic
Ni. The observed changes are consistent with the behaviour of the spin
resonance mode as seen by inelastic neutron scattering in YBCO. This strongly
suggests that the "peak-dip-hump" and the "kink" in ARPES on the one side and
neutron resonance on the other are closely related features.
