摘要：

We present results of our magneto-optical studies of excitonic transitions in narrow GaAs quantum wells, i.e., in the case when the heavy-hole-light-hole splitting is significantly larger than the heavy-hole exciton binding energy. The main (s-type) heavy-hole transitions can be simply understood in terms of two-dimensional hydrogeniclike magnetic levels. A giant repulsion occurring between the 3d- heavy-hole and the Is light-hole states demonstrates the importance of Coulomb interaction in the mixing of magnetoexcitonic levels.
