摘要：
The spin-singlet and spin-triplet optical transitions of negative donor centers D- in GaAs/(Al,Ga)As quantum wells in high magnetic fields are considered both theoretically and experimentally. The measured and calculated transition energies are shown to be in very good agreement for the D- singlet transition (1%). The two strong triplet transitions that are predicted by theory are ndt observed in the experiment. This is thought to be due to accidental energy coincidences with one-particle excitations such as the electron cyclotron resonance and the 1s --> 2p(+) transition of neutral donors.
