Abstract
Light scattering from screened single-particle electron excitations has been observed in GaAs, InP, and CdTe. The intensity, polarization properties, and temperature dependence of the single-particle scattering in GaAs are compared with effective-mass calculations based on nonparabolic as well as parabolic bands. The experimental results are in disagreement with present theory.Keywords
