|Abstract:||The preferred fragmentation patterns of negatively charged carbon clusters, C−N have been investigated by cluster beam impact methods using various surfaces and impact energies (Ei = 0-150 eV). Transitions from one type of cluster structure to another are inferred from the observed change in fragmentation patterns. The results are made possible by the high intact-scattering yield of C−N clusters, and by the competitiveness of fragmentation with electron emission for clusters N 33, for which electron emission dominates over fragmentation. These results are compared and contrasted with results obtained from other fragmentation and collisional methods.|
