Abstract

Nickel ions generated by sputtering with argon plasma are irradiated to fullerene C60, 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.

Keywords
