“…Secondly the internal structures of the projectile and the target will give rise to various exchange effects [31,32,33,34]. These effects will be more prominent at higher energies and must be accounted for by an inclusion of exchange terms in the Hamiltonian [35,36,37]. An even fuller approach would be to replace the Coulomb potential with more realistic interactions [38,39,40].…”

Rutherford scattering is usually described by treating the projectile either classically or as quantum mechanical plane waves. Here we treat them as wave packets and study their head-on collisions with the stationary target nuclei. We simulate the quantum dynamics of this one-dimensional system and study deviations of the average quantum solution from the classical one. These deviations are traced back to the convexity properties of Coulomb potential. Finally, we sketch how these theoretical findings could be tested in experiments looking for the onset of nuclear reactions.
