Abstract
Experimentally, Raman continuum for and geometry exhibits peaks far apart from each other (about 80 to 150 ) in frequency. The former is insensitive to doping over a small range where does not vary much whereas the latter shifts towards higher frequencies. We calculate the electronic Raman scattering intensities using the `modified spin bag model'. We show that the calculated results have natural explanation to the observed anamolous peak separation and peculiar doping dependence.
