| Abstract: |
With the ALADIN forward spectrometer the fragmentation of gold
nuclei at 600 MeV per nucleon after interaction with carbon,
aluminum, copper, and lead targets has been investigated. The
results are compared to quantum-molecular-dynamics (QMD)
calculations using soft and hard equations of state as well as a
soft equation of state with momentum-dependent forces. Whereas the
QMD has been successfully applied to heavy ion collisions at lower
energies, it is not possible to reproduce the fragment
distributions and the light-particle multiplicities observed in
this experiment at relativistic energies. To study the reasons for
the discrepancy between the experimental data and the simulations
we investigated the time evolution of the nuclear system after a
collision and the disintegration pattern of excited nuclei in
the QMD approach.
