Title: MULTIPHONON RESONANT RAMAN-SCATTERING IN A STRONG MAGNETIC-FIELD
Author: TRALLEROGINER, C

Abstract: Explicit expressions for multiphonon resonant Raman scattering processes in a strong magnetic field are derived in the framework of a quasiclassical picture, where the photoexcited electron and hole make real transitions through the LO-phonon Frohlich interaction. It is shown that spin quantization produces a strong selection rule in different scattering configurations and the calculated magneto-Raman profile shows a set of sharp peaks that correspond to outgoing resonances. The principal features of the magnetomultiphonon spectra observed recently in GaAs and InP are discussed. These results are compared with experimental magneto-Raman profiles for 2-LO-phonon emission in two scattering configurations. From this comparison a value of the light-hole g factor equal to +22 is obtained.
