AbstractThe fragment production in collisions of Ca-48,Ca-50+C-12 at 50 MeV/nucleon are simulated via the isospin-dependent quantum molecular dynamics (IQMD) model followed by the GEMINI code. By changing the diffuseness parameter of neutron density distribution to obtain different neutron skin sizes, the effects of neutron skin thickness (delta(np)) on projectile-like fragments (PLFs) are investigated. The sensitivity of isoscaling behavior to neutron skin size is studied, from which it is found that the isoscaling parameter a has a linear dependence on delta(np). A linear dependence between delta(np) and the mean N/Z [N (Z) is neutron (proton) number] of the PLF is obtained as well. The results show that thicker neutron skin will lead to smaller isoscaling parameter alpha and N/Z. Therefore, it may be probable to extract information of neutron skin thickness from isoscaling parameter alpha and N/Z.
