摘要：

Experimental results on the structure of carbon cluster anions and cations with 20 and 24 atoms are presented. Recent quantum chemical calculations predict either cage or graphitic structures to be lowest in energy for C20 and C24. However experimentally we find C20+ and C20- are dominated by monocyclic ring structures, with C20- exhibiting minor amounts of planar bicyclic structures and a linear structure. For C24+ and C24- both monocyclic rings and planar bicyclic rings are observed. No fullerene or ''graphitic'' structures are observed for these clusters. A number of possible bicyclic structures for C24 are discussed.
