Abstract: | The 140~MeV/u ^40,48Ca+^9Be and ^58,64Ni+^9Be
reactions are simulated by the statistical abrasion ablation model,
and the simulation results are compared to the National
Superconducting Cyclotron Laboratory (NSCL) experimental data. By
comparing the fragment isotopic distributions of ^40,48Ca and
^58,64Ni, we study the isospin effect in the projectile
fragmentation induced by the neutron-rich nuclei at intermediate
energy experimentally and theoretically. It is found that the
isospin effect in projectile fragmentation decreases and even
disappears as the violence of the collision increases. |
