摘要：

Internal spin-singlet and spin-triplet transitions of charged excitons X- in magnetic fields ill quantum wells have been studied experimentally and theoretically. The allowed X- transitions are photoionizing and exhibit a characteristic double-peak structure, which reflects the rich structure of the magnetoexciton continua in higher Landau levels (LLs). We discuss a novel exact selection rule, a hidden manifestation of translational invariance, that governs transitions of charged mobile complexes in a magnetic field. (C) 2000 Elsevier Science B.V.
