Photon, Electron, and Secondary Ion Emission from Single C₆₀ keV Impacts

This Letter presents the first observation of coincidental emission of photons, electrons, and secondary ions from individual C₆₀ keV impacts. An increase in photon, electron, and secondary ion yields is observed as a function of C₆₀ projectile energy. The effect of target structure/composition on photon and electron emissions at the nanometer level is shown for a CsI target. The time-resolved photon emission may be characterized by a fast component emission in the UV−Vis range with a short decay time, while the electron and secondary ion emission follow a Poisson distribution
