Formation of carbon-rich molecules by fast ion impact

To study ion impact induced reactions yielding carbon-rich molecules so called polyynes and fullerenes, n-hexane and n-octane solvent near the melting point were set in rough vacuum conditions and irradiated by a 2 MeV ion beam of H+, or H_2^+. The solid carbon materials and the hydrocarbon vapor were also used as a target. The irradiated samples were analyzed by UV spectroscopy and high performance liquid chromatography. Ion-induced reactions of C_70 solution, polyyne solution and the solid C_60 were also performed.
