Abstract
High resolution resonant Auger spectroscopy applied to the core excitation of reveals that the kinetic energy of the spectator Auger electrons stays constant when the photon energy is scanned through the B resonance, whereas the kinetic energy of participator Auger electrons shows a linear photon energy dependence. These nondispersive and dispersive effects are theoretically reproduced using a quasi-Jahn-Teller model and by treating the Auger emission process as a coherent second-order quantum process.
