Isospin dependence of projectile fragmentation and neutron-skin thickness of neutron-rich nuclei

  • By investigating the cross section distributions of fragments produced in the 140 A MeV 40,48Ca+9Be and 1 A GeV 124,136Xe+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 136Xe+208Pb reaction is calculated. By adjusting the diffuseness parameter in neutron density distribution of 136Xe, we find the isospin dependence of projectile fragmentation in fragment production is sensitive to the neutron-skin thickness of the projectile nucleus.

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