摘要：

The dispersion curves of the B exciton-polariton in CdS have been studied for k⊥c by resonant Brillouin scattering. Evidence is obtained for three propagating polariton modes for E⊥c. A preliminary analysis incorporating an energy term linear in wavevector is in agreement with the measured dispersion of the Brillouin shifts. © 1979.
