| Abstract | The present study deals with the extraction of the symmetry energy from heavy-ion collisions at intermediate energies. Using the isospin quantum molecular dynamical (IQMD) model, the dependence of the sum of the charge number for fragments with Z >= 2(Z(bound)) on the multiplicity of neutrons (M-n) from the projectile spectator fragmentation of Sn-124 and La-124 at 600 MeV/nucleon is compared with the experimental results of the ALADIN-2000 Collaboration. The comparison suggests a soft symmetry energy. In addition, the sensitivities of the symmetry energy toward the Z(bound) dependence on proton multiplicity (M-p), neutron-to-proton single [R(n/p)] and double ratio [R-D (n/p)], are also examined. The Z(bound) dependence of R(n/p) is found to be the most sensitive observable toward the symmetry energy. The ALADIN Collaboration should extend the results for R(n/p) in the near future. |
