Experimentally the Raman continuum in the superconducting state of hig
h T-c materials for the A(g) and B-g geometry of scattering exhibits p
eaks far separated from each other (about 80 to 150 cm(-1)) in frequen
cy. The former insensitive to doping variations over a small range nea
r the optimal doping concentrations, where the T-c does not vary much,
whereas the latter shifts towards higher frequencies for lesser hole
concentrations. It is also observed that the peak position for the A(g
) continuum is very temperature sensitive, whereas the peak position o
f the B-g geometry scattered intensity is only weakly dependent on tem
perature. We calculate the electronic Raman scattering intensities usi
ng the ''modified spin bag model'', and show that it offers a natural
and quantitative explanation for the anomalous peak separation and the
ir peculiar sensitivity to doping variations as well as to temperature
