Radioactive heterofullerenes As*C59, As*C69(As*=71As, 72As, 74As), 69GeC59, and their polymers are detected by using radiochemical and radiochromatographic techniques. This result suggests that a carbon atom in fullerene molecule can easily be substituted with As or Ge by a recoil process following nuclear reactions. Using ab initio molecular-dynamics simulations based on the all-electron mixed-basis approach, we confirmed that the formation of a substitutionally doped heterofullerene with a single As atom is really possible.
