Collision dynamics using neutron rich and deficient Sn + Sn collisions with 270MeV/u

Heavy-ion collisions are utilized to investigate nuclear EOS worldwide because it is a unique tool to analyze nuclear EOS under supra-saturation density in laboratories. Various observables are proposed and measured as sensitive probes to investigate the symmetry energy in the dense matter produced by heavy-ion collisions. We have performed experiments using Sn isotope beams. nucleus+nucleus collisions for ¹³²Sn+¹²⁴Sn and ¹⁰⁸Sn+¹¹²Sn, and ¹²⁴Sn+¹¹²Sn at 270 MeV/u was carried out to study system dependence with different isospin asymmetries and a common total charge.

In this talk, we discuss the observables related to the light-charged particles, including stopping power, collective flow, and the free neutron/proton ratio comparing three systems.

The results offer further insights into the dynamics of heavy-ion collisions and the cluster formation process, which is beneficial in a comprehensive understanding of the nucleus+nucleus collision dynamics and nuclear EOS.
