Abstract: | The internal transitions of two-dimensional (2D) excitons in a high magnetic field B exhibit features due to the coupling of the internal and center-of-mass motions. A study is made of these features, and it
is shown that for magnetoexcitons with a center-of-mass momentum K ≠0 the energies of the strong transitions decrease with increasing K, and the absorption spectra show weakly resolved transitions, whose total intensity depends strongly on the exciton statistics
(distribution function).
