中能核反应中粒子产生的模型:应用于95 MeV/nucleon的C-C碰撞

A model for particle production in nuclear reactions at intermediate energies: application to C-C collisions at 95 MeV/nucleon

Jérémie Dudouet, Dominique Durand

摘要:

本文提出了一个描述中能核碰撞的模型,并与最近测量的95 MeV/核子C-C反应双微分截面作了比较。结果表明,几何效应和入口通道的记忆,特别是两个入射核的动量分布所起的关键作用。特别注意的是发生在中快度的过程的描述。为此,在两个相互作用的核的重叠区域中,考虑了通过速度空间中的聚结过程的随机粒子产生机制。

英文摘要:

A model describing nuclear collisions at intermediate energies is presented and the results are compared with recently measured double differential cross sections in C-C reactions at 95 MeV/nucleon. Results show the key role played by geometrical effects and the memory of the entrance channel, in particular the momentum distributions of the two incoming nuclei. Special attention is paid to the description of processes occurring at mid-rapidity. To this end, a random particle production mechanism by means of a coalescence process in velocity space is considered in the overlap region of the two interacting nuclei.
