Abstract
Raman light scattering with excitation of electron-hole continuum and a phonon is investigated theoretically. The effect of a surface and sc reening of the electron-photon coupling and of the deformation potenti al as a result of the Coulomb interaction of the electrons is taken in to account. The parameters of the 340 cm(-1) resonance line in superco nducting YBaCuO are estimated by comparing with experimental data.
