Rezumat

Resonance Roman scattering by exciton polaritons in crystals of CuGaS 2 under excitation with the 4880 and 4765 Å lines of an Ar + laser at 9 K is studied. Lines of one- and two-phonon scattering of excitonic polaritons are found and studied. It is shown that the 1LO and 2LO phonons are arranged in accordance with their energies as the Stokes shifts move farther away from the excitation energy.
