摘要：

The energies and wave functions of impurity (defect) states which appear in the energy gap of La2CuO4 due to doping are calculated by the unrestricted Hartree-Fock method. It is shown that the state vectors have such a structure that localized carriers (holes) can occupy not only oxygen ions but also copper ones.
