Metallofullerene is one of promising material for the drug delivery system transporting useful encapsulated atoms, such as radioisotopes, with their characteristic cage-like structure. The methods to synthesize radioactive metallofullerenes are, for example, to irradiate cold metallofullerenes by thermal neutrons in a nuclear reactor and to prepare metallofullerene by an arc discharge method using radioisotopes created by an accelerator. However, the radioactive metallofullerenes synthesized these methods are including many amount of non-radioactive carriers and radioisotopes are dispersed into not only targeted fullerene species but also various kind of other species. In this study, we tried to synthesize radioactive metallofullerenes of carrier-free and single molecular species using the nuclear recoil technique by high energy neutron irradiation.
