  For a set of realistic nucleon-nucleon potentials we evaluate microscopic
parameters of binary collisions: a time duration of the scattering state, a
mean distance and a rotation of nucleons during a collision. These parameters
enter the kinetic equation as non-instantaneous and non-local corrections of
the scattering integral, i.e., they can be experimentally tested. Being
proportional to off-shell derivatives of the scattering T-matrix,
non-instantaneous and non-local corrections make it possible to compare the
off-shell behavior of different potentials in a vicinity of the energy shell.
The Bonn one-Boson-exchange (A-C) and Paris potentials are found to yield very
close results, while the separable Paris potential differs.
