Abstract
The matrix elements of bilocal currents are calculated in instanton vacuum model. The classification of currents according to the nature of coupling with vacuum fields is analyzed. It is also shown that in the axial channel the direct instanton-antiinstanton contributions that smoothed out strong asymmetry in quark momenta distribution in mesons are essential. 14 refs.; 4 figs.
