Pauli blocking plays an important role in the nucleus-nucleus collisions at low and intermediate energies as the available phase space volume is quite small. Since the available momentum phase space is huge and more than 95% produced particles are bosons Pauli blocking plays an important role in the nucleus-nucleus collisions at low and intermediate energies as the available phase space volume is quite small.
