标题： Role of the density-dependent symmetry energy in multi-fragmentation

摘要： 在不同入射能量下，使用含约化同位素依赖截面的同位素依赖量子分子动力学模型研究弹体和 spectators 物质的碎裂。利用对称能密度依赖性的不同参数化分析碎片产生的敏感性。我们还将强调动量依赖相互作用（MDI）和对称能在中间能量下对碰撞核碎裂的集体响应。 显示英文摘要

摘要： The fragmentation of projectile and spectator matter is studied at different incident energies using an isospin-dependent QMD model with reduced isospin dependent cross-section. The sensitivity of the production of fragments is analyzed using different parametrizations of density dependence of symmetry energy. We shall also highlight the collective response of the momentum dependent interactions(MDI) and symmetry energy towards the fragmentation of colliding nuclei at intermediate energies.
