Abstract：
In the framework of Quantum Molecular Dynamics model the individual nucleon behavior(regular or chaotic)in the intermediate energy heavy ion reactions is investigated.The correlation between the nucleon behavior and the reaction fragmentation mechanism is analysed.The nucleon motion in the evolution process of a compound nuclear system showed regular behavior.The coexistance of the regular trajectories and the chaotic ones suggests that the regular regions in the interaction area embed in irregular ones,reflecting the fractal nature of the repellor,and indicating the existance of local stable potential generated by intermediate mass fragment.The appearance of more instable trajectories associated with the decreasing number of nucleon and small cluster emission.The chaotic nucleon motion began earlier than the time when the system may reach the region of mechanical instability characterized by equation of state of nuclear matter.
