“…This is because the calculations with smaller L can reach a higher density in the overlap region, and thus, more compressional energy is stored than for the calculations with large L. Thus, the reaction system simulated with smaller L disintegrates into more light fragments compared to the case of the calculations with large L. Owing to the conservation of the nucleon number in the reaction system, the production of projectile-like residues with A > 100 calculated with larger L is higher than with a smaller L. It is consistent with the calculations in Refs. [74,75].…”

To improve the constraints of symmetry energy at subsaturation density, measuring and accumulating more neutron skin data for neutron-rich unstable nuclei is naturally required. Aiming to probe the neutron skin of unstable nuclei by using low-intermediate-energy heavy-ion collisions, we develop a new version of an improved quantum molecular dynamics model, in which the neutron skin of the initial nucleus and the mean-field potential in nucleon propagation are consistently treated. Our calculations show that the three observables, such as the cross-sections of the primary projectile-like residues with A>100 (σA>100), the difference of σA>100 between 132Sn + 124Sn and 124Sn + 124Sn systems (δσA>100), and the neutron-to-proton yield ratio (R(n/p)) in the transverse direction, could be used to measure the neutron skin of the unstable nuclei and to constrain the slope of the symmetry energy in the future.

“…ρ n and ρ p are the neutron and proton densities, respectively, and δ = (ρ n − ρ p )/(ρ n + ρ p ). In theory, large uncertainties of density dependence of the symmetry energy away from normal nuclear matter are predicted and it stimulates lot of efforts to constrain isospin asymmetric nuclear equation of state, especially the density dependence of symmetry energy S(ρ) in past 30 years [125][126][127]. Generally, constraints of symmetry energy can be obtained from the investigation of properties of nuclear structure, heavy ion collision and neutron stars.…”
