Giant Electron-Phonon Anomaly in Doped and Other Cuprates
Figure 24
Data of [74] for the 1 symmetry. (a) Phonon spectra at 300 K and 10 K. The main difference with [73] and Figure 22 is a bigger energy range here: 42–75 meV in [74] versus 51–72 meV in [73]. (b) The difference between the intensity at 57 meV and the average of intensities at 53 meV and 49 meV at Q = (0, 3.25, 0). Temperature dependence above not seen in Figure 22 comes from including of the 49 meV phonon, which falls outside the energy range investigated in [73] and shown in Figure 22(a).
