Notizen: Abstract Structure and stability of carbon clusters in the size range 50≤n≤72 have been investigated by means of a semiempirical many body potential (Tersoff, J.: Phys. Rev. Lett.61, 2879 (1988)). The ground state geometries, identified by Monte Carlo Simulated Annealing, may be described as slightly distorted hollow spheres, with nearly graphitic atomic arrangement. Starting from these structures, we simulate by Molecular Dynamics a series of cluster-cluster collisions. The final aim of these computations is to simulate the deposition of carbon clusters produced in a molecular beam on a graphite surface. Our preliminary results indicate that at leastC 60 could survive the deposition process.
