• The magnetic-nonmagnetic transition of impurities in semiconductors isstudied by a simple one-dimensional model. The model is a two-electron systemin a linear chain with a short-range imptu'ity potential v. The intra-site two-bodyrepulsive energy U is assumed tlu'oughout the crystal. The phase boundary forthe transition is calculated ntunerically exactly by the use of the Green's functionformalism. In contrast with the model of Mattis and Lieb, the singlet groundstate becomes degenerate with the lowest one-electron scattering state (magnetic)for practically all value of v as U exceeds a critical value U. which is of the sameorder of magnitude as v.
