Abstract
To investigate the problem of the 'flat continuum' in the normal state Raman scattering from single crystals of YBa2Cu3O7(YBCO), the value of the intraband Raman scattering from single crystals of crystal has been obtained and compared with the Raman crosssection for the unscreened part of the single-particle electronic excitations. It is found that only in the highly collision-dominated regime, it is possible to obtain close- to-flat continuum, as a contribution from heavily damped plasmon excitations in the system involving extremely large values of the normal state collision frequency ωc(ω).
