Collision Direction Dependence of React ion Channels and Reaction Products in Molecular Collisions Between Two C₆₀ Molecules

The reaction channels and the reaction products in the collisional reactions between two C₆₀ molecules are found to be sensitively dependent on the relative orientation between the colliding partners. The detailed collision processes and the stable structures of the products are studied by using a molecular dynamics simulation method combined with a Langevin molecular dynamics scheme. The defects of the reaction products are also analyzed.
