Description
The density as well as momentum dependences of the symmetry potential in nuclear matter can be studied using the collective flow parameters in intermediate energy nuclear collisions, where mean-field dynamics and nucleon–nucleon collisions compete. The directed and elliptic flow parameters for light charged particles in Xe + Sn collisions at 100 MeV/u, measured by the INDRA detector, have been analyzed. The experimental data are compared with the ImQMD transport model calculations, employing two Skyrme interactions with and without applying the GEMINI++ afterburner. This comparison allows us to systematically study the momentum-dependence of the symmetry potential and secondary decay effects. This presentation also includes some prospects for the current efforts to further develop our understanding of the nuclear symmetry energy.
