Projectile Fragmentation of 36,40Ar Induced Reactions

Fragment yields for Z ≥ 5 from projectile fragmentation using primary beams of ^36,40Ar at 50 MeV/nucleon on ⁶⁴Ni target have been measured in RIBLL fragment separator. We compare the fragment cross sections with the predictions of the empirical EPAX parametrization of fragmentation cross-sections and Statistical Abration-Ablation model (SAA) by considering the RIBLL separator transmission rate. Isotope yield ratios between these two reactions were calculated and isoscaling parameters α and β are extracted, their dependences on fragment atomic number Z and neutron number N were presented.
