Resumo: Raman scattering from polaritons was studied near resonance in ZnSe. Detailed dispersion curves were determined experimentally for different incident frequencies and compared with theoretical results. Measurements of linewidth and relative scattered intensities were also performed. The observed polariton dispersion curves showed a deviation from theory near the same frequencies for which line broadening occurred, indicating the necessity of including relaxation effects depending on polariton frequency. Structure in the polariton intensity as a function of frequency, not observed before, may also be related to damping.
