Emissions of free neutrons and protons from the central collisions of 124Sn+124Sn and 112Sn+112Sn reactions are simulated using the Improved Quantum Molecular Dynamics model with two different density dependence of the symmetry energy in the nuclear equation of state. The constructed double ratios of the neutron to proton ratios of the two reaction systems are found to be sensitive to the symmetry terms in the EOS. The effect of cluster formation is examined and found to affect the double ratios mainly in the low energy region. In order to extract better information on symmetry energy with transport models, it is therefore important to have accurate data in the high energy region which also is affected minimally by sequential decays.

  1. Investigating the possibility of extracting neutron-skin thickness in nuclei by their collisions at intermediate energies

    In simulated intermediate-energy tin collisions, the free neutron-to-proton yield ratio is more sensitive to the symmetry potential than to the initial neutron-skin thickness in most kinematics.
