标题： Molecular dynamics approach: from chaotic to statistical properties of compound nuclei

摘要： 混沌散射在经典模型的$\alpha$-簇核中的统计特性被研究。 发现由双曲不稳定性所支配的动力学导致生存概率呈指数衰减，最终演化为一个极限能量分布，其密度呈现出玻尔兹曼形式。 相应衰变产物的角分布相对于$\pi/2$角具有对称性。 复合核形成的时间估计在$10^{-21}$秒的数量级内。 显示英文摘要

摘要： Statistical aspects of the dynamics of chaotic scattering in the classical model of $\alpha$-cluster nuclei are studied. It is found that the dynamics governed by hyperbolic instabilities which results in an exponential decay of the survival probability evolves to a limiting energy distribution whose density develops the Boltzmann form. The angular distribution of the corresponding decay products shows symmetry with respect to $\pi/2$ angle. Time estimated for the compound nucleus formation ranges within the order of $10^{-21}$s.
