Assuming that the shallow‐impurity wave function is composed of the states of a single Landau subband, an effective one‐dimensional wave equation is derived and discussed in detail, allowing for the band anisotropy. The optical transitions from the bound impurity states to both, bound and free‐carrier states are considered. For strong effective‐mass anisotropy, e.g. for acceptors in semimagnetic semiconductors, the energies and wave functions are explicitly given for all impurity states.
