Consistent Constraint

The reaction mechanism of the central collisions and peripheral collisions for 112,124 Sn + 112,124 Sn at E/A = 50 MeV is investigated within the framework of the Improved Quantum Molecular Dynamics model. The results show that multifragmentation process is an important mechanism at this energy region, and the influence of the cluster emission on the double n / p ratios and the isospin transport ratio is important. Furthermore, three observables, double n / p ratios, isospin diffusion and the rapidity distribution of the ratio R7 for 112,124 Sn +112,124 Sn at E/A = 50 MeV are analyzed with the Improved Quantum Molecular Dynamics model. The results show that these three observables are sensitive to the density dependence of the symmetry energy. By comparing the calculation results to the data, the consistent constraint on the density dependence of the symmetry energy from these three observables is obtained.

Threshold Energies

The threshold energies of radial flow in central collisions are investigated within an isospin dependent quantum molecular dynamics model using three different forms of symmetry energy. It is found that the neutron-rich system had smaller threshold energy of radial flow and this quantity depends on the form of symmetry potential. It indicates that the threshold energy of radial flow can provide a new method to determine the symmetry energy of asymmetric nuclear matter.
