Abstract：
The isoscaling behavior in projectile fragmentation has been systematically investigated by a modified statistical abrasion-ablation (SAA) model. The reduced isoscaling parameters are found to decrease with the excitation energy per nucleon and have no significant dependence on the size of reaction systems. Assuming a Fermi-gas behavior, the excitation energy dependence of the symmetry energy coefficients are tentatively extracted from α and β which looks consistent with the experimental data.
