Title

Thermionic Emission and Fragmentation of C60

Abstract

We analyze the rate of delayed (thermionic) ionization of photoexcited C60 molecules. The rate has a power-law dependence, indicating the presence of a continuum of rate constants. The value of the exponent provides information about the competition between delayed ionization and unimolecular fragmentation; it is equal to the ratio of the ionization energy and the activation energy for fragmentation. This result provides a novel method to measure the controversial bond dissociation energy of neutral C60. We obtain a value of 11.9±1.9eV.
