摘要：The heavy-ion phase-space exploration （HIPSE） model is used to discuss the origin of the nuclear spin in intermediate energy heavy-ion collision （HIC）.The spin of maximal projectile-like fragment is found to depend strongly on impact parameter of a reaction system,while it relates weakly to the collision violence.Some interesting multi-fragmentation phenomena related to the spin are shown.We also found that the excitation energy in the de-excitation stage plays a robust role at the de-excitation stage in HIC.
