Abstract

The \ensuremathπ^\ensuremath-/\ensuremathπ⁺ ratio is examined as a function of isospin asymmetry and beam energy for central collisions induced by neutron-rich nuclei within an isospin-dependent hadronic transport model. The \ensuremathπ^\ensuremath-/\ensuremathπ⁺ ratio is found to increase with the isospin asymmetry, but decrease with the beam energy of the reaction. For neutron-rich systems, such as, ¹²⁴Sn+¹²⁴Sn and ¹³²Sn+¹²⁴Sn, the sensitivity of \ensuremathπ^\ensuremath-/\ensuremathπ⁺ ratio to nuclear symmetry energy is almost beam energy independent.
