T. Moriwaki et al., COLLISION-INDUCED ELECTRON DETACHMENT OF CARBON CLUSTERS, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 37(2), 1996, pp. 169-174
The collisional electron detachment process of carbon cluster anions c
ontaining from 2 to 72 atoms was investigated on the collision with a
MoS2 surface. The detachment efficiency was classified into several gr
oups and is most likely to reflect the structures or the isomer conten
ts of the incident cluster anions. The cluster anions produced via las
er-vaporization of graphite showed guile a larger detachment efficienc
y than the fullerene C-60(-) and its fragment anions. The major isomer
s of these cluster anions were suggested to be chains or rings.
