Dh. Yu et al., FORMATION AND FRAGMENTATION OF C(N)-60( CLUSTERS PRODUCED FROM A C)C-70 MIXTURE IN AN ELECTRON-IMPACT ION-SOURCE/, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 29(1), 1994, pp. 53-59
Various fullerene ions are generated in a standard plasma ion source f
rom a vaporized mixture of C60/C70. Except C60+ and C70+, the fulleren
e ions are formed by fragmentation of C60 or C70 excited by electron i
mpact. Information on the structure and stability of the fullerene ion
s is obtained by studying unimolecular dissociation and collision-indu
ced fragmentation of C60+, C58+ and C56+ in H-2 and Ar target gases.
