Abstract: With in the framework of distance dependent tight-binding molecular dynamics (DDTBMD), the collision dynamics of sodium cluster Na n has been studied systematically. Some phenomena have been observed at different impact parameters b , such as fusion reaction, deep inelastic collision (DIC) and quasi-elasticcollision, which are similar to the nuclear heavy-ion collisions (HIC). For the system of Na6 (3D) + Na8, the reaction mechanism at b=9a0 is DIC, but when b is equal to 13a0, it corresponds to quasi-elastic collision. Further more the rotation processes during the collisions, are related to the collision energy and parameter. The larger collision energy is, the earlier relative rotation will occur, and the relaxation time becomes shorter and the relative rotation energy is much smaller. There exists maximal relative rotation energy which corresponding to b = 7a0. When b is smaller than 7a0, the rotation energy increases with b increasing, otherwise the energyd ecreases. And the maximal relative rotation energy is corresponding to DIC process. The maximal rotation energy can reach on etenth of total energy, which is much less than that in HIC.
