摘要
在量子分子动力学模型计算多重碎裂基础上,应用阶乘矩方法分析了多重碎裂.对(197)An(200MeV/u)+(197)An碰撞系统进行了计算.发现多重分布有阵发混沌存在.并对临界现象做了初步讨论.
The method of scaled factorial moments is used to study fluctuations of the fragment-size distribution based on the quantum molecular dynamics model. From the calculation of 197An (200MeV/u) +197Au central collision system, an intermittent pattern of fluctuations is found. In particular, the critical behavior is preliminarily discussed.
