Projectile fragmentation reactions have been investigated by the modified statistical abrasion-ablation model (SAA) and the heavy-ion phase-space exploration (HIPSE) model. From the fragment yield ratios, clear isoscaling behavior was observed in the calculated results of the two models. The extracted isoscaling parameters alpha and beta for both heavy and light fragments from HIPSE model calculations are in better agreement with recent experimental data than the SAA model. Assuming a Fermi-gas behavior, the excitation energy dependence of the symmetry energy coefficients are extracted from alpha and beta, which looks consistent with the experimental data.
