Excitation, intraband, effect

As this review is primarily concerned with low-energy electronic scattering in the normal and superconducting states of high-rc superconductors, it is useful to consider in detail the cross-section for Raman scattering from intraband electronic excitations. Using eqs. (6) and (7), the electronic Raman scattering cross-section can be related to a correlation function associated with an effective density p.
