The correlation functions (polarization operators) of colorless currents are calculated over the entire range of (Euclidean) momenta in the instanton vacuum of quantum chromodynamics. The appearance of a pion pole due to the spontaneous breaking of chiral invariance is studied explicitly. The mass and the axial constant of the ..pi.. meson, f/sub ..pi../, are calculated in terms of the parameters found previously for the instanton medium.
