A time-of-flight mass spectrum of the C<sub>60</sub> and C<sub>70</sub> fullerenes with the use of a vacuum ultraviolet H<sub>2</sub> laser photoionization source is presented. The photon energy is 7.8 eV, approximately 0.2 eV above the reported ion thresholds of both molecules. This relatively low excess energy is believed to be insufficient for fragmentation, as demonstrated by production of only parent ions.
