N1 - Funding Information:
This work was partly supported by the REIMEI, Research Resource of Japan Atomic Energy Research Institute and by the Grant-in-Aid for the Ministry of Education, Culture, Sports, and Science of Japan. We thank the crew of the JAERI Tandem accelerator for providing the 6Li ion beam for production of the radiotracer.

N2 - We have, previously, reported on the HPLC elution behavior of the Th, Pa, U, Np, and Am metallofullerenes and the UV/vis/NIR absorption spectra of the Th@C84 and U@C82 species. In this paper, the followings are reported: (1) Pu metallofullerenes were produced and their HPLC elution behavior was investigated using a radiotracer technique. The HPLC chromatogram of this metallofullerene was found to be almost the same as that of the Np and Am metallofullerenes. (2) The oxidation states of Th@C84 and U@C82 produced in macroscopic quantities were examined by XANES (X-ray absorption near edge structure) measurements. The oxidation state of the U atom in the C82 fullerene cage was estimated to be 3+ with the formal charge of the ionic molecule being U3+@C823-.
