Abstract:

An improved method is proposed for the extraction of the symmetry energy coecient relative to the temperature,
asym=T, for the heavy-ion reactions near the Fermi energy region, based on the modified Fisher Model
(MFM). This method is applied to the primary fragments of the Anti-symmetrized Molecular Dynamics (AMD)
simulations for the reactions of 40Ca + 40Ca at 35MeV/nucleon. The density and the temperature at the fragment
formation stage are extracted using a self-consistent method.
