Nickel ions generated by sputtering with argon plasma are irradiated to fullerene C 60, and the possibility of synthesizing nickel atom endohedral fullerene is demonstrated. The mass spectra of the samples analyzed by laser desorption/ionization mass spectrometry are similar to a calculated isotope distribution ratio of the nickel atom endohedral fullerene. The optimum ion irradiation energy is approximately 35 eV, which corresponds to the energy expected by the molecular dynamics simulations.
