We calculate the production cross sections of different fragments for reactions of 112Sn＋112Sn and 124Sn＋124Sn at different beam energies. The species and production cross sections of neutron-rich isotopes are generally dependent on the isospin of the system and the incident energies. The isotopes 48Ca and 54Ca are more productive for the neutron-rich system at 30 to 150 MeV/nucleon.展开更多
