Abstract

The thermal electron emission rate constant for C$_{60}^-$ has been deduced over a range of 4 eV internal energy from storage ring measurements of the decays of ions reheated with single photons absorption. The thermal radiation from the ions is quantified with respect to continuous cooling and discrete photon quenching.
