  Gas phase C$_{70}$ molecules have been ionized with single photons of
energies between 16 eV and 70 eV and the electron spectra measured with
velocity map imaging in coincidence with the ions. The doubly ionized and
unfragmented species was present at photon energies of 22 eV and up, and triply
charged ions from 55 eV. The low kinetic energy parts of the spectra are
explained with thermal emission of transient hot electrons. Deviations at high
photon energies are used to determine a value for the initial electron
equilibration time. We propose a generally applicable mechanism, named
Resonance Ionization Shadowing, for the creation of hot electrons by absorption
of above-threshold energy photons.
