摘要：

Recent experiments involving fullerene ions in a storage ring are discussed. Storage times of the order of 2 to 10 s set by collisional destruction in the background gas were observed. Short-lived components related to metastability of some of the ions were observed and are related to thermionic emission and unimolecular fragmentation. The long storage time may lead to ''cold'' cluster beams. An example (photodetachment) where this quality is utilized is also discussed.
