Role of the nuclear symmetry potential and Coulomb potential is explored on the peak energy of intermediate mass fragments (Ec.m.max) and on peak multiplicity (NIMFsmax) and their dependence on mass asymmetry of the reaction is also investigated. The calculations are done using Isospin-dependent Quantum Molecular Dynamics (IQMD) model. We also showed that the momentum-dependent interactions have uniform effects of Ec.m.max and these effects are independent of mass asymmetry of the reaction. Further, we see that isospin effects that enter through the Coulomb and symmetry potential show much significant role as one increases the mass asymmetry of reaction. Mass asymmetric reactions thus serve a sensitive tool to investigate the nuclear symmetry energy effects.

不对称碰撞中峰值碎片产生中库仑和对称势的相互作用

探讨了核对称势和库仑势对中等质量碎片峰值能量的作用（乙C.米.最大限度）和峰值多重性（ñ国际货币基金组织最大限度) 以及它们对反应质量不对称性的依赖性也进行了研究。计算是使用 Isospin 依赖的量子分子动力学 (IQMD) 模型完成的。我们还表明，动量相关的相互作用对乙C.米.最大限度这些影响与反应的质量不对称无关。此外，我们看到通过库仑和对称势进入的同位旋效应显示出非常重要的作用，因为它增加了反应的质量不对称性。因此，质量不对称反应是研究核对称能量效应的敏感工具。
