| Abstract: | The magnetooptic absorption spectra of high-quality homoepitaxial GaAs layers in a magnetic field B up to 7.5 T at T=1.7 K are investigated. It is shown that the Fano effect is involved in the formation of certain lines of the magnetooptic
spectrum. The parameters of the phenomenological Fano function are determined. It is shown that polariton effects of the diamagnetic
exciton play a significant role in the investigated processes.
