    "abstract": "The isospin effect and isoscaling behavior in projectile fragmentation have\nbeen systematically investigated by a modified statistical abrasion-ablation\n(SAA) model. The normalized peak differences and reduced isoscaling parameters\nare found to decrease with ($Z_{proj}-Z$)/$Z_{proj}$ or the excitation energy\nper nucleon and have no significant dependence on the size of reaction systems.\nAssuming a Fermi-gas behavior, the excitation energy dependence of the symmetry\nenergy coefficients are tentatively extracted from $\\alpha$ and $\\beta$ which\nlooks consistent with the experimental data. It is pointed out that the reduced\nisoscaling parameters can be used as an observable to study excitation extent\nof system and asymmetric nuclear equation of state in heavy ion collisions.",
