Abstract：
The cross sections of the fragments produced in the projectile fragmentation reactions of the even calcium isotopes from A=36 to A=52 are calculated using the statistical abrasion ablation model. The neutron skin thickness are studied by investigating the fragments isotopic cross section distributions. The neutron-skin thicknesses of the calcium isotopes have a good linear correlation to the peak positions of their fragment isotopic cross section distributions. The correlation between the neutron skin thickness and the neutron density distributions of ⁴⁸Ca is investigated by introducing a parameter to adjust the diffuseness parameter in the fermi-type density distribution.
