The N 1s core electron shake-up and the shake-up Auger satellite spectrum of the N2molecule

The shake-up Auger satellite spectrum associated with the N 1s Auger spectrum of N 2 is recorded using monochromatized X-ray excitation. As many as 11 structures are observed in the spectrum. Assignments in terms of participator and spectator processes are discussed based on data from normal Auger and shake-up spectra and from a simple one-particle model. The interpretation is assisted also by a new N 1s photoelectron shake-up spectrum showing several hitherto unobserved details. A new X-ray excited normal Auger electron spectrum of N 2 is also presented.
