Abstract
We theoretically study resonant hyper-Raman scattering of light by 2 LO phonons in a CdS crystal with the wurtzite structure. The scattering process involving the two-photon dipole transitions to B and C excitons of the s-type is considered. The different sequences of intermediate states are taken into account. It is shown that the inclusion of the possible dipole transitions to the deeper valence band, at certain conditions, can have a noticeable effect on the frequency dependence of the scattering cross section.
