Multiphonon resonant Raman scattering up to four phonons in GaSe and one and two phonon resonant Raman scattering in the mixed GaS/sub x/Se/sub 1 - x/ crystals with x less than or equal to 0.23 were investigated. The results can be explained by a simple theory in which the dispersion of the resonance behavior is mainly dominated by resonances with the 1s direct exciton state.
