摘要：

The existence of C(60)7+ and spontaneous decay of this ion via the superasymmetric fission reaction C-60(7+) --> C-58(6+) + C2+ have been observed and studied by isotope-resolved two-sector-field mass spectrometric techniques, thereby allowing the unambiguous identification of the septuply charged fullerene ion and the experimental determination of the rather large kinetic energy release of 9.7 +/- 2.2 eV for the separating fragment ions.
