Abstract

Raman light scattering with excitation of electron-hole continuum and a phonon is investigated theoretically. The effects of a surface are studied. The screening of the electron-photon coupling and of the deformation potential as a result of the Coulomb interaction of the electrons is taken into account. Two limiting cases of a low and large spatial dispersion of charge transfer fluctuation are considered. The parameters of the 340 cm−1 line and the electron-phonon constant in YBaCuO are estimated by comparing with an experiment.
