Abstract
The collision between a copper dimer and an Ar film is investigated by molecular-dynamics simulations. A dimer fragmentation rate of 24% is found for an impact kinetic energy of 25 eV per atom, in agreement with previous experimental results. Temporary dissociation of the dimer followed by a reaggregation is observed in 14% of the cases. The collision induces a fast superheating of the Ar film around the impact point followed by a liquefaction. The cooling rate of the copper dimer is found to be one order lower than the cooling rate of the Ar film in the impact area.
