Resumen:
We found the emission of high- energetic electrons by He+ colliding on a HOPG surface. By allowing the population of the excited state of He, in a calculation that takes into account properly the correlation effects, we found the population of excitonic states in HOPG that, through autoionization, provides a possible source for the observed high energy electrons.The theoretical calculations allow us not only to explain the presence of high energy electrons in the secondary spectra, but also provide a mechanism to explain the high neutralization probability of He+ on HOPG observed in ISS experiments.
