摘要
在量子分子动力学模型中考虑了同位旋依赖的对称能项和库仑相互作用项，讨论了对称能对２０Ｎｅ（３０ＭｅＶ／ｕ）＋２０Ｎｅ和２８Ｎｅ（３０ＭｅＶ／ｕ）＋２０Ｎｅ对头碰撞系统质量分布及集团形成的影响。
The interaction terms of the isospin-dependent symmetric energy and Coulomb energy are considered in the quantum molecular dynamics. The effects of thesymmetric energy on the mass distribution and cluster formation in the head oncollisions of the systems 20Ne+20Ne and 28Ne+20Ne at the incident energy of 30MeV/u are discussed, and the favorable condition for synthesizing neutron-rich isotopes is predicted.
