Abstract

A scaling phenomenon in the cross section for fragments has been found in the projectile fragmentation reaction, and an empirical scaling formula is proposed by considering the dependence of cross section on the size and asymmetry of the reaction system and the fragment itself. Furthermore, the empirical scaling formula is used to predict the production of fragment in the ⁶⁸Ni/⁶⁹Cu/⁷²Zn + ⁹Be reactions around 90A MeV. Compared to the results calculated by the statistical abrasion ablation model and the \sc epax3 parameterizations, the empirical scaling formula can better reproduce the measured fragments. The empirical scaling formula can be used to predict the yield for fragment in projectile fragmentation reaction.
