摘要：

The two-body effects for a Mott-Wannier exciton in a magnetic field are investigated. For excitons with nonvanishing pseudomomentum there exists an outer potential well which contains a class of weakly bound and delocalized quantum states. The spectrum and eigenfunctions in this potential well are calculated in a harmonic approximation.
