| Abstract | In the framework of a modified statistical abrasion-ablation (SAA) model, the isospin effect and isoscaling behavior in projectile fragmentation have been systematically investigated. The normalized peak differences and reduced isoscaling parameters are found to decrease with (Z(proj)-Z)/Z(proj) and have no significant dependence on the size of reaction systems. The linear dependence of alpha and vertical bar beta vertical bar on Delta[(Z/A)(2)] or Delta[(N/A)(2)] for projectile-like fragments is demonstrated, which is obtained for light fragments from multifragmentation in the grand-canonical limit. Assuming a Fermi-gas behavior, the excitation energy dependence of the symmetry energy coefficients are tentatively extracted from alpha and beta which looks consistent with the experimental data. It is pointed out that the reduced isoscaling parameters can be used as an observable to study the excitation extent of system and asymmetric nuclear equation of state in heavy ion collisions. |
