  • 摘要: 在重离子碰撞(HICs)的实验数据和动力学模拟的反应中发现了丰中子余核产额的标度现象。在这种标度现象中,两个同位旋不同的炮弹碎裂反应产生的余核中,不同中子丰度差的余核的信息熵不确定度的差具有一致的分布。利用反对称化分子动力学模型(AMD)模拟并联合退激发模型(GEMINI)模拟了140 AMeV 58,64Ni+9Be碰撞体系中余核的产额,并展示了实验测量的余核已经理论模拟得到的余核的标度现象。由于信息熵方法对反应系统是否处于平衡状态没有要求,不仅可以用于处于平衡态系统的核物质研究,也可以用于动力学变化过程中的核物质性质研究。信息熵方法将为HICs中的核物质演化研究提供新的理论分析方法。


    A scaling phenomena has been discovered for fragments produced in heavy-ion collisions both in the measured experiments and in the simulated reactions by transport model. In this scaling phenomena, the information entropy uncertainty difference between isobars with different neutron-excess has a uniform distribution between two reactions. The simulated reactions of 140 AMeV 58,64Ni+9Be by using the asymmetric molecular dynamics(AMD) model plus the sequential decay code GEMINI are analyzed to show the scaling phenomena of fragments. Since the application of information entropy theory does not require the system to be in equilibrium, it can be used both in the analysis of transport model and thermodynamics models. The advantage of the information entropy theory provides a new method to study the dynamical evolution of nuclear matter inheavy-ion collisions.
