Abstract：
The effect of collective rotation and the reaction characteristics are studied for intermediate energy heavy ion Collision. The maximum impact parameter, the reaction centrality, the average collective rotation energy and the angular velocity,which characterize the heavy ion collisions, are deduced. For 10.6 MeV/u ⁸⁴Kr+²⁷Al→¹¹¹In fission reaction, it is found that this reaction has high degree of collision centrality. the average collective rotation energy is larger than one-third of the total excitation energy, and the composite nuclear system rotates about 8.8 turns before breakup.
