Light scattering intensities by the polaritons of F2-type in GaAs have been experimentally studied. The spectra were excited by an YAG: Nd3+ laser in the infrared. When using the scattering intensities derived from the polar TO- and LO-phonons as input data for calculations, the k-dependent intensities in the polariton region could be verified within less than a few percent. The intensity variation for larger wave vectors was more precisely to be determined and verified than the frequency shifts.
