  The problem of electron binding states in field of two D0 centres in
semiconductive quantum well (QW) in the presence of an external longitudinal
magnetic field (along the QW growth axis) is studied within the framework of
zero-range potential model. It is found that the magnetic field leads to a
considerable change in positions of g- and u-terms, and to a stabilization of
the D2- states in QW. It is shown that a form of impurity magneto-optical
absorption spectrum essentially depends on the light polarization direction and
on the spatial configuration of the D2- molecular ion in QW.
