Abstract:

Evidence is presented for the presence of a shakedown satellite near threshold in the CKVV Auger spectrum of graphite. Its origin is shown to be an electron in a relatively long-lived valencecore excitonic level populated as a result of dynamic core-hole screening which participates in the Auger decay. Modeling the shakedown contribution considerably improves agreement in the threshold region between the experimental lineshape and a simple one-electron model. Keywords Auger Spectroscopy, Graphite, Dynamic screening, and Shakeup.
