Abstract: Mass spectrum of negative cluster carbon ions with cluster size up to 100 was recorded on a self-built laser plasma source time-of-flight mass spectrometer. For cluster anious larger than or equal to 50, only clusters with even size were observed. This observation suggests that these cluster anions can also adopt the fullerene configuration and the configuration transition from planar ring to closed shell starts at n=50. Among these anions, C_(60)~- does not have special ion intensity.

Key words: Carbon cluster, Negative ion, Fullerene
