Collision Direction Dependence of React ion Channels and Reaction Products in Molecular Collisions Between Two C_(60) 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.
