The photoelectron spectra of C-60 produced with three different generation methods were recorded with 6.4eV photon energy using a magnetic-bottle-type time-of-flight photoelectron spectrometer. From these spectra, it was suggested that the laser vaporization of a graphite rod mainly produces C-60 of ring-like structure. On the other hand, C-60 produced by the fragmentation process of the fullerene C70 through C2 or C2n elimination give different photoelectron features from those of C-60 having an icosahedral (Ih) symmetry or a ring-like structure.
