%X Discrete states of conduction electrons bound to ionized acceptors are observed in intraband magneto-optical experiments on Be-doped GaAs/Ga0.67Al0.33As quantum wells. The electrons are bound to acceptors by a joint effect of the quantum well and an external magnetic field. The observed transition energies are successfully described using states of single magnetoacceptors. The energies show evidence for oscillatory screening of acceptor potentials. Also, two disorder modes of the cyclotron resonance related to acceptor potential fluctuations are observed at higher filling factors.
