Title

Electron Impact Ionization and Dissociation of Neutral and Ionized Fullerenes

Abstract

Three different types of electron impact ionization experiments have been performed, involving neutral and charged C60 and C70. 1) We have determined absolute partial ionization cross sections for formation of parent ions C z+60 and C z+70 in charge states up to z = 4, and of singly and multiply charged fragments of size n ≥ 44 and n ≥ 50 from C60 and C70 neutral precursors, respectively. 2) Previous appearance energy measurements of C70 have been improved and extended to z = 5; ionization energies are found to depend linearly on the charge state of the precursor, in agreement with theoretical predictions. 3) A beam of mass selected C 2+60 has been crossed with an intense electron beam; the induced reactions (fragmentation, post- ionization, and dissociative post-ionization) have been analyzed.
