N2 - Systematic angle-resolved photoemission spectroscopy (ARPES) has been performed on Bi2Sr2Can-1CunO 2n+4 (n=1-3). For n=2 and 3, the dispersion kink becomes pronounced on approaching (π, 0) below Tc, while a kink appears only around the nodal direction above Tc. This indicates that the coupling of electrons with magnetic resonance mode plays a dominant role in the superconducting state for multi-layered cuprates. Ultrahigh-resolution (ΔE=1.3 meV) ARPES result for n=2 indicates that spectra around (π, 0) below Tc is understood in terms of (1) the coupling of electrons with the resonance mode, (2) the real-space inhomogeneity, and (3) the impurity states in the vicinity of EF.
