Quantitative Comparison between Electronic Raman Spectra and Angle-resolved Photoemission Spectra in Superconducting State of Bi2212

In this paper we present the calculations of electronic Raman scattering (ERS) spectra for B1 g and B2 g geometries using angle- resolved photoemission spectroscopy (ARPES) spectra of nearly optimally doped cuprate superconductor Bi2Sr2CaCu2O8 (Bi2212), Tc=92K. Calculations were taken on the Fermi surface (FS) in the superconducting state at temperature well below Tc and the results were quantitatively compared to the experimental data. It shows that there is a good agreement in B1 g while the peak position in B2 g is about 100 cm-1 lower than the experimental one. This result indicates that the scattering rate is not large enough to explain Raman spectra and additional contribution should be taken into account to reproduce ERS spectra.
