Popis:	The temperature dependence of the photoreflectance spectra of multiple quantum wells has been measured. The low-temperature spectra show structure beyond what would be expected from a finite-well model. Not only are allowed and forbidden transitions observed, but also features which may be due to additional critical points introduced by complexities in the valence band. The temperature dependence of the linewidth of the 11H exciton is reported.
