Query: Resonant Enhancement of Inelastic Light Scattering in the Fractional
  Quantum Hall Regime at $\nu=1/3$   Strong resonant enhancements of inelastic light scattering from the long
wavelength inter-Landau level magnetoplasmon and the intra-Landau level spin
wave excitations are seen for the fractional quantum Hall state at $\nu = 1/3$.
The energies of the sharp peaks (FWHM $\lesssim 0.2meV$) in the profiles of
resonant enhancement of inelastic light scattering intensities coincide with
the energies of photoluminescence bands assigned to negatively charged exciton
recombination. To interpret the observed enhancement profiles, we propose
three-step light scattering mechanisms in which the intermediate resonant
transitions are to states with charged excitonic excitations.
