Formation of fullerene(C$$_{60}$$) by laser ablation in superfluid helium at 1.5K

Aratono, Yasuyuki; Wada, Akira*; Akiyama, Kazuhiko; Kitazawa, Shinichi; Hojo, Kiichi; Naramoto, Hiroshi*

C$$_{60}$$ fulleren was detected in the deposit produced by the laser ablation in superfluid helium at 1.5K. From the mass spectrometry, it was found that the ratio, $$^{12}$$C$$_{60}$$/$$^{12}$$C$$_{59}$$$$^{13}$$C, differs from statistical one calculated by Poisson distribution for natural graphite. Assuming the recombination of atomic carbons to C$$_{2}$$ molecules as an initial stage for C$$_{60}$$ formation, the different isotopic ratio of C$$_{60}$$ from Poisson statistics was ascribed to the tunneling recombination between $$^{12}$$C and $$^{13}$$C atoms in the bubble state.
