Single-photon ionization of higher fullerenes C76, C78 and C84. Determination of ionization potentials

Abstract The ionization of higher fullerenes by single-photon excitation with synchrotron radiation has been investigated in a molecular beam experiment using the time of flight technique. Ionization potentials for the higher fullerenes C 76 , C 78 and C 84 have been determined from photoionization efficiency spectra for these molecules. The measured values are 7.10±0.10 eV for C 76 , 7.05 ± 0.10 eV for C 78 and 7.15±0.10 eV for C 84 .
