标题： Dynamics of many-particle fragmentation in a Cellular Automaton model

摘要： 一个由作者开发的3D细胞自动机模型，用于处理N体相互作用的动力学，已被调整以研究两个相同结合粒子团簇的正面对撞及其随后的碎片化过程。 选择的撞击能量范围足够低，以确保可以形成复合结合团簇。 该模型设计用于模拟由4pi探测器监测的碎片实验的实验室设置。 粒子通过Lennard-Jones势相互作用。 在低撞击能量下，遵循单个粒子动力学的数值实验表明，所有复合团簇粒子之间存在能量共享阶段。 然后发现所有尺寸的碎片从该团簇中蒸发出来。 在我们的设置中，通过模拟的4pi探测器测量的团簇尺寸符合指数约为2.6的幂律。 显示英文摘要

摘要： A 3D Cellular Automaton model developed by the authors to deal with the dynamics of N-body interactions has been adapted to investigate the head-on collision of two identical bound clusters of particles, and the ensuing process of fragmentation. The range of impact energies is chosen low enough, to secure that a compound bound cluster can be formed. The model is devised to simulate the laboratory set-up of fragmentation experiments as monitored by 4pi detectors. The particles interact via a Lennard-Jones potential. At low impact energies the numerical experiments following the dynamics of the individual particles indicate a phase of energy sharing among all the particles of the compound cluster. Fragments of all sizes are then found to evaporate from the latter cluster. The cluster sizes, measured in our set-up by simulated 4pi detectors, conform to a power law of exponent around 2.6.
