  The cross section of hard diffractive dissociation of the pion into two jets
is calculated. It is obtained that the distribution of longitudinal momenta for
jets is not simply proportional to the profile of the pion wave function, but
depends on it in a complicated way.
  In particular, it is shown that, under the conditions of the E791 experiment,
the momentum distribution of jets is similar in its shape for the asymptotic
and CZ wave functions, and even the ratio of the differential cross sections is
not far from unity.
