. Dans-ce-paragraphe, A cette occasion, nous allons mettre enévidenceenévidence une divergence qualitative entre le comportement des systèmes et celui des noyaux lors des collisions. Pour ce faire, nous avons tracé les corrélations entre l'´ energie cinétique totale de l'´ evénement et l'angle absolu entre l'axe du " faisceau " et l'axe principal de l'ellipso¨?deellipso¨?de de la collision. Le calcul de cet ellipso¨?deellipso¨?de est expliqué au 3.2.2. Pour une collision donnée, il s
