Duration and nonlocality of a nucleon-nucleon collision

For a set of realistic nucleon-nucleon potentials we evaluate microscopic parameters of binary collisions: time duration of the scattering state, mean distance, and rotation of nucleons during a collision. These parameters enter the kinetic equation as noninstantaneous and nonlocal corrections of the scattering integral, i.e., they can be experimentally tested. Being proportional to off-shell derivatives of the scattering T matrix, noninstantaneous and nonlocal 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 and Paris potentials are found to yield very close results, while the separable Paris potential differs.
