Manifestations of the Electron-Phonon Coupling in
the Spectroscopy of High-Temperature Superconductors
Figure 7
Low-energy part of the spectral function. Spectra of normal, isotope substituted, and “anti-isotope’’ substituted compounds are drawn by solid, dotted, and dashed lines, respectively. (a), (c), (e) and (g), (i), (l) correspond to nodal and antinodal points. Insets (b), (d), (f), (h), and (k) show the peak corresponding to real quasiparticle.
