聚变和转移反应中的核-核势、能量耗散和质量弥散

Nucleus-nucleus potential, energy dissipation and mass dispersion in fusion and transfer reactions

Kouhei Washiyama, Denis Lacroix, Sakir Ayik

摘要:

从微观平均场动力学出发,得到了聚变反应中的核-核势和能量耗散。推导的电位很好地再现了从实验数据中提取的电位。能量耗散在不同的反应中表现出普遍的行为。在随机平均场动力学模型下,研究了转移反应中质量分布的色散。通过引入集体空间中的初始涨落,色散的描述比仅用平均场的描述有了很大的改进。结果与实验数据的宏观唯象分析相一致。

英文摘要:

The nucleus-nucleus potential and energy dissipation in fusion reactions are obtained from microscopic mean-field dynamics. The deduced potentials nicely reproduce the one extracted from experimental data. Energy dissipation shows a universal behaviour between different reactions. Also, the dispersion of mass distribution in transfer reaction is investigated in a stochastic mean-field dynamics. By including initial fluctuations in collective space, the description of the dispersion is much improved compared to that of mean field only. The result is consistent with the macroscopic phenomenological analysis of the experimental data.
