Ein semiklassisches Transportmodell, nämlich das Modell der Quantenmolekulardynamik (QMD)-Modell, wird für die theoretische Untersuchung der Kerndynamik bei Au197 + Au197-Kollisionen bei verschiedenen Strahlenergien von 20 bis 1000 MeV/Nukleon und bei Stoßparametern von b = 0 bis 13 fm unter Verwendung einer weichen Zustandsgleichung (EOS) herangezogen. Insbesondere untersuchen wir verschiedene Größen wie die mittlere und maximale Dichte, das Anisotropieverhältnis, Teilnehmer-Zuschauer-Materie, den relativen Impuls, die Rapiditätsverteilung, die Kollisionsrate sowie den Zeitpunkt der maximalen Dichte und deren Abhängigkeit von der Energie und dem Stoßparameter. Unsere Ergebnisse zeigen eindeutig eine signifikante Abhängigkeit aller Größen von der Energie und dem Stoßparameter. Der Zeitpunkt der maximalen mittleren Dichte und der maximalen Dichte folgt einem Potenzgesetz mit der Einfallsenergie. Interessanterweise haben wir beobachtet, dass die Variation des Stoßparameters bis zu 400 MeV/Nukleon zu einer drastischen Veränderung der Teilnehmer-/Zuschauer-Materie führt, während jenseits von 400MeV/Nukleon wurden Ergebnisse gefunden, die nahezu unabhängig vom Stoßparameter sind.
