Relative activation energies for dissociation of fullerene ions Cnz+ into Cn−2z+ + C2 have been determined for z = 1 and 2, covering the size range 52 ≤ n ≤ 70. These data are derived from measured appearance energies of fragment ions, obtained

The observation of sequential attachment of two electrons to the ${\mathrm{C}}_{84}$ molecule and the subsequent autodetachment of the ${\mathrm{C}}_{84}$ dianion is reported. Remarkably, the cross section for attaching the second electron is estimat

Using recently measured accurate relative partial ionization cross section functions for production of the C60 fragment ions C+58 through C+44 by electron impact ionization, we have determined the respective binding energies BE(C+n–C2), with n=58,.

The multiphoton ionization photoelectron spectrum (MPI-PES) of C[sub 60] using pulsed lasers of nanosecond duration shows prompt electrons resulting from direct two-photon ionization, as well as a dominant low-energy delayed electron signal which fol

Two methods are described for obtaining activation energies for evaporation from isolated clusters. They involve measurements of (1) kinetic energy distributions during evaporation and (2) metastable decay probabilities. The two methods supplement ea

Beginning with rather basic principles, general relations are obtained for evaporative rate constants. These are established both as a function of energy and of temperature. In parallel with this, expressions are developed for the kinetic energy dist

The formation of positive and negative ions in the all-carbon-cage fullerene molecules C 60 and C70 has been studied using both electron beams and laser beams. Structures in the low energy electron attachment cross section for C 60 occur from the nea

A technique for measuring the time‐resolved delayed electrons and C+n ions from C60 excited by nanosecond or picosecond laser irradiation is presented. Ions produced well after the laser pulse (delayed ionization) are mainly C+60 with weak signals

Thermal electron attachment to nitromethane, methylcyanide, methyliodide, and methylbromide is compared with capture of electrons by these molecules from highly excited Rydberg states of atoms. Data on thermal electron attachment to CH3NO2 are consis
