对称碰撞中中等质量碎片的产生

Intermediate Mass Fragment Production In Symmetric Collisions

Anupriya Jain, Bahadur Singh, Suneel Kumar

摘要:

本文对重离子碰撞中的多重碎裂及其相关现象进行了系统的理论研究。本研究是在一个同位旋相关的量子分子动力学模型(IQMD)和使用最小生成树(MST)算法。通过数值模拟研究了不同参数对多重数、质量分布、弹靶质量与碰撞参量的依赖关系以及弹靶质量与IMF产生量的依赖关系等的影响。观察到货币基金组织的多重性的上升和下降。结果与ALADIN的实验数据进行了比较,发现是在密切的协议。

英文摘要:

We present a complete systematic theoretical study of multifragmentation and its associated phenomena in heavy ion collisions. This study is performed within an Isospin dependent Quantum Molecular Dynamical Model (IQMD) and using Minimum Spanning Tree (MST) algorithm. Simulations are carried out to study the different parameters like time evolution of multiplicity, mass distribution, impact parameter dependence and IMF's production dependence of projectile & target mass. The rise and fall in multiplicity of IMF's is observed. Results are compared with experimental data of ALADIN and are found to be in close agreement.
