费米能区重离子碰撞的动力学描述

Dynamical description of heavy-ion collisions at Fermi energies

P. Napolitani, M. Colonna

摘要:

描述费米能下的重离子碰撞需要考虑介质内耗散和相空间涨落。这些相关性与单体集体行为的相互作用决定了出口通道的性质(运动学和碎片产生)和各种机制(从融合到颈部形成和多重碎片化)。从测试核物质的基本概念出发,我们建立了一个微观描述,解决有限的系统,并适用于实验观测。

英文摘要:

Descriptions of heavy-ion collisions at Fermi energies require to take into account in-medium dissipation and phase-space fluctuations. The interplay of these correlations with the one-body collective behaviour determines the properties (kinematics and fragment production) and the variety of mechanisms (from fusion to neck formation and multifragmentation) of the exit channel. Starting from fundamental concepts tested on nuclear matter, we build up a microscopic description which addresses finite systems and applies to experimental observables.
