Identification of satellites due to resonant excitation and shake-off in the CKVVAuger line shape of polyethylene

A quantitative interpretation of the C KVV Auger line shape of polyethylene reveals the presence of satellites arising from resonant excitation into a core excitonic state and from shake-off of a valence electron during the initial core ionization. The intensity, energy, and shape of these satellites reveal much about localization and screening processes in one-dimensional polymers.
