我们提出了一个完整的系统学（激发函数和系统大小的依赖性）的全球停止和侧流的重离子反应的能量范围在0.09A和1.93A GeV之间。对于最重的系统，Au+Au，我们观察到一个平台的最大停止从约0.2A到0.8A GeV的两侧快速下降。停止的程度，这是保持显着低于预期的一个完全停止的情况下，被发现是高度相关的量的侧流。
We present a complete systematics (excitation functions and system-size dependences) of global stopping and side flow for heavy ion reactions in the energy range between 0.09A and 1.93A GeV. For the heaviest system, Au+Au, we observe a plateau of maximal stopping extending from about 0.2A to 0.8A GeV with a fast drop on both sides. The degree of stopping, which is shown to remain significantly below the expectations of a full stopping scenario, is found to be highly correlated to the amount of side flow.
