摘要：
By investigating the cross section distributions of fragments produced in the 140 A MeV Ca-40,Ca-48+ Be-9 and 1 A GeV Xe-124,Xe-136+Pb reactions, the isospin dependence of projectile fragmentation in fragment production is studied. In the framework of the statistical abrasion-ablation model, the 1 A GeV (136)xe+Pb-208 reaction is calculated. By adjusting the diffuseness parameter in neutron density distribution of Xe-136, we find the isospin dependence of projectile fragmentation in fragment production is sensitive to the neutron-skin thickness of the projectile nucleus.
