Abstract
The total amplitude of the two-phonon resonant Raman scattering in a high magnetic field is calculated in a model with uncorrelated electrons and holes having equal effective masses (InBr,InI, light-hole-to-electron transitions in GaAs). The importance of the role of this mechanism compared to the scattering via the discrete states of hot excitons is discussed. The cross section as a function of magnetic field and (or) laser frequency shows resonances resulting from electron and hole transitions to the vicinity of the Landau-band bottom in the real intermediate states. The influence of lifetimes of incoming and outgoing transitions in the scattering efficiency is discussed.
