Production Cross Section of Neutron-Rich Calcium Isotopes in Heavy Ion Collisions

Based on the isospin-dependent quantum molecular dynamics model along with the GEMINI model, heavy-ion collisions at intermediate energies are studied. 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 nucleon 48Ca and 54Ca are more productive for the neutron-rich system at 30 to 150 MeV/nucleon.
