| Abstract: | 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. |
