Abstract

Using the quantum molecular dynamics approach we have started to analyze the results of the recent INDRA experiments at GSI experiments. For the first time we could identify a midrapidity source in which fragments are formed from a almost identical fraction of projectile and target nucleons. In smaller systems we have not found this source. Nevertheless the fragment spectra at small and large angles are completely determined by the dynamics. We discuss how fragments are formed in the different regions of phase space and what they tell us about the reaction mechanism.

多片段反应中片段的起源
使用量子分子动力学方法,我们已经开始分析最近在GSI实验中进行的INDRA实验的结果。我们第一次发现了一个中速源,其中碎片是由几乎相同的弹丸和靶核子组成的。在较小的系统中,我们还没有发现这个来源。然而,小角度和大角度的碎片光谱完全由动力学决定。我们讨论了碎片是如何在相空间的不同区域形成的,以及它们告诉我们的反应机理。
