One subset of the fullerene activities is collision experiments using high energetic inert gases with fullerene clusters. We report on the formation of fullerene oligomers upto (C60)m , m=2-12 following the collisions of 200 keV and 400 keV Xe with (C60)55 fullerene clusters using classical reactive dynamics. A preference for C60+n (n=1-4) fragments was observed after the collision. The sequence of peaks detected in the range C105 - C122 after 1 ns from the collision is comparable with the experimental results. According to the post collisional dynamics, a dimer formed with one cross-link between two fullerenes led to a peanut shaped molecule after 25 ns and a linear trimer has turned into a carbon nanotube like structure after 43 ns. At the ns time scale, more organized carbon molecules as well as big amorphous carbon chunks also remained as collisional products.
