摘要：

Excitation spectra of a high-quality wide GaAs/AlAs quantum well have been measured in a magnetic field up to 6 T. The spectra are distinguished by a complicated fine structure which depends strongly on magnetic field. By comparing the results with theoretical calculations which take into account exciton-mixing effects, most of the peaks observed in the spectra can be assigned. The high-resolution spectra of a selected anticrossing clearly indicate that a complicated many-exciton-mixing model is essential to explain the excitation spectra of wide quantum wells. © 1990 The American Physical Society.
