Oh the collision dynamics of Na cluster with different geometry
几何构型不同的Na团簇碰撞动力学研究

Using the distance dependent tight binding molecular dynamics model (DDTB MD), the Na 6 (2 D )+Na 8,Na 6(3 D )+Na 8 collision dynamic processes have been studied for different incident energies and different impact parameters.Different reaction mechanisms have been observed, such as fusion reaction, deep inelastic and quasi elastic collisions, which are similar to the nuclear heavy ion collisions. This shows that the clusters with different geometric structures colliding with identical clusters can produce different new clusters. At lower incident energy central collisions, Na 6(3 D ) can form a stable cluster;at leV/ n half central collision, Na 6(3 D ) is easy to form a larger cluster.
