Pauli correlations in heavy-ion collisions at high energies

We calculate the effects of short-range correlations on the Glauber expansion for nucleus-nucleus collisions using the Fermi gas model for nuclei. When we neglect the Pauli principle for collisions between heavy nuclei, calculation of the optical phase-shift function leads to non-unitary results and we cannot obtain cross sections. When we include Pauli correlations we find important cancellations in the optical phase-shift function, which make possible the calculation of total and differential cross sections for heavy nuclei.

Collisions between atomic systems

Abstract We calculate the scattering amplitude for elastic and inelastic collisions between arbitrary ions or neutral atoms by means of an expansion of a generalization of the Glauber approximation for particle-atom collisions.
