Abstract
The Quantum Molecular Dynamic method is used to study the influence of the equation of state (EOS), in-medium n-n cross sections and momentum dependent interactions (MDI) on the main observables of heavy ion collisions. The procedure how to extract the equation of state from these observables is presented. Therefore we show, that the in-medium n-n cross sections can be measured by comparing the rapidity distributions of singles and fragments with the results of microscopic calculations for light systems (A < 40).
The transverse flow distribution p x(Y), in contrast to the flow angle distributions dN/dcosθF, is shown to depend strongly on the equation of state but also on the n-n cross sections and the MDI. We show, that the MDI have only minor influences at lower bombarding energies (E ≤ 200MeV/nucl.). Higher bombarding energies do not lead to an drastic increase of the central density and therefore the EOS could be fixed at least with a finite uncertainty by comparing the excitation function of the transverse flow with all available microscopic calculations.
