The specific intranuclear (including neutron and proton) density distributions were introduced into the Abrasion-Ablation model, and the modified model was used to calculate the projectile fragmentation in the 30MeV / u 40 Ar + natAg reaction. The results show that there is a significant difference between the modified model and the pre-correction calculation in the very peripheral collision, which reflects the influence of the edge density of the nuclear density.Compared with the experimental results, The energy of the fragmented fragments relative to the reduction of the beam energy is caused by the frictional effect.
