Abstract
Effect of normal impurities in superconductors whose gap function is o dd in k - k(F) are analyzed. A superconductivity is possible in this c ase even in the presence of an arbitrarily strong point repulsion betw een electrons. This circumstance is attractive from the standpoint of a theory for the high-T(c) superconductivity of metal oxides. Impuriti es lead to an extremely strong suppression of this pairing-stronger th an in the case of magnetic impurities in conventional superconductors.
