Abstract
The fragment production in collisions of 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 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 has a linear dependence on . A linear dependence between and the mean [ is neutron (proton) number] of the PLF is obtained as well. The results show that thicker neutron skin will lead to smaller isoscaling parameter and . Therefore, it may be probable to extract information of neutron skin thickness from isoscaling parameter and .
