The structures of the low-energy isomers of neutrals, cations, and anions, together with the fullerenes corresponding to their outer cages.
The binding energy as a function of (a) cluster size and (b) . In (a), the squares stand for the anions, circles for neutrals, filled triangles for cations, and the opened triangles for the experimental values with shift of . In (b), the circles stand for the values of the calculated binding energies and the lines are guide to the eyes.
The inverse mobilities (in ) of silicon cations in the size range 31–50. Filled circles are the calculated values within the exact hard sphere scattering model, where the values in red circles are those of the best isomers reported in Refs. 23 and 24. Opened circles are the measured values.
Binding energies of the neutrals, cations, and anions of the best isomers of . The isomers notated with “a” are the new isomers we found. The isomers notated with “R1” and “R2” are those proposed in Refs. 23 and 24, respectively.
The predicted dissociation channels of silicon cluster cations and anions in the range . Several channels with energy differences of less than are given.
