Abstract
As a temporal approach a method of examining occurrence of nuclear collisions is exploited in terms of the wave packet description. The off-shell scattering matrix element characteristic of the method governs the time and position when reactions take place during interactions. For a plain exemplification we consider occurrence of relativistic nucleon-nucleus scattering in the Dirac phenomenology. The results indicate that at higher intermediate energies the forward scattering occurs before the peak of the nucleon probability density reaches the center of the nuclear interaction region.
