关于重离子碰撞中的热化

On the thermalization achieved in heavy-ion collisions

Sukhjit Kaur, Aman D. Sood, Rajeev K. Puri

摘要:

我们用硬状态方程和cugnon截面以及MSTB方法对近对称和非对称体系的中心反应进行了模拟,得到了产生最大IMF的能量(E $_{c.m.}^{peak}$)。我们研究了碎片的各种性质。通过持续性系数和增益项来检验碎片的稳定性。通过相对动量、各向异性比和快度分布,得到了重离子碰撞中热化和停止的信息。我们发现,一个完全停止的传入核非常重的系统是必需的。

英文摘要:

We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using hard EOS along with cugnon cross section and employing MSTB method for clusterization. We study the various properties of fragments. The stability of fragments is checked through persistence coefficient and gain term. The information about the thermalization and stopping in heavy-ion collisions is obtained via relative momentum, anisotropy ratio, and rapidity distribution. We find that for a complete stopping of incoming nuclei very heavy systems are required.
