The formation of heavier atoms (Sb,Te)-incorporated fullerenes has been investigated by using radionuclides produced by nuclear reactions. From the trace of radioactivities of (formula presented) (formula presented) or (formula presented) after high-performance liquid chromatography, it was found that the formation of endohedral fullerenes or heterofullerenes in atoms of Sb or Te is possible by a recoil process following the nuclear reactions. To confirm the produced materials, ab initio molecular-dynamics simulations based on an all-electron mixed-basis approach were carried out. We present the possibility of the formation of endohedral fullerenes or substitutional heterofullerenes incorporated with Sb or Te atoms.
