Abstract
Results are reported of a new type of experiment in which a heavy ion storage ring is utilized to cool fullerene ions, C-60(-) and C-70(-) a nd to carry out laser photodetachment experiments in order to measure the electron affinities of ions possessing the minimum amount of inter nal energy. Fullerene negative ions are stored in the ring for periods of up to 5 s, and the time evolution of the electron affinity is meas ured, yielding limiting values of 2.666 +/- 0.001 and 2.676 +/- 0.001 eV for cold C-60(-) and C-70(-), respectively.
