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 *** interesting multi-fragmentation phenomena related to the spin are *** also found that the excitation energy in the de-excitation stage plays a robust role at the de-excitation stage in HIC.
