Rezumat

We consider a superconductor in which coupling between the conduction band electrons and the electrons of an impurity is realized by the tunneling of the Cooper pairs. We investigate the mode in which such tunneling influences the critical temperature Tc of the superconductor. It is found that in some conditions the presence of impurity may lead to the increase of Tc.
