摘要：

Highly fluorinated fullerenes of the composition C60Fx with x = 46, 48 and C70Fx with x = 54, 56 have been ionised by single photon absorption. The resulting ions have been detected by means of time-of-flight mass spectrometry. For all species under investigation, the careful analysis of the photo-ion yield curves at threshold revealed identical ionisation energies of 12.0 eV with an uncertainty of +/- 0.1 eV for the C-60-based molecules and +/- 0.2 eV for the C-70-based ones.
