标题： Signals of bimodality in the fragmentation of Au quasi-projectiles

摘要： 在35 AMeV的Au+Au碰撞中产生的准投影体衰变的实验数据中已经研究了双峰性的信号。 同一数据集已经被证明提供了多个一阶液-气相变特征的信号。 分析了近期文献中提出的不同事件排序方法。 通过最大碎片电荷分布揭示了碎片模式的突然变化，这与双峰行为相容。 显示英文摘要

摘要： Signals of bimodality have been investigated in experimental data of quasi-projectile decay produced in Au+Au collisions at 35 AMeV. This same data set was already shown to provide several signals characteristic of a first order, liquid-gas-like phase transition. Different event sortings proposed in the recent literature are analyzed. A sudden change in the fragmentation pattern is revealed by the distribution of the charge of the largest fragment, compatible with a bimodal behavior.
