Effect of Pauli Blocking on Exchange and Dissipation Mechanisms Operating in Heavy-Ion Reactions

Systematic properties of dissipation and exchange mechanisms associated with damped nuclear reactions are obtained from available data, yielding results that cannot be consistently described in a classical approach. However, correlations between energy loss and the variances of the fragment $A$ and $Z$ distributions are understood on the basis of an exchanged-induced dissipation mechanism, if account is taken of the Pauli exclusion principle.
