N2 - We have applied both high-resolution photoelectron and Auger spectroscopy to study the N 1s core ionization of N2. From the respective spectra we are able to show that the Auger decay involves delocalized description of core-hole states. Specifically, the Auger spectra of the N 1sσ g,u core holes to the quasi-stable final states X1Σ +g and D1Σ+u are presented. They exhibit the gerade/ungerade splitting as well as vibrational progressions. The 1sσg/1sσu Auger intensity ratios are, in agreement with ab initio calculations, ≅2.1 and ≅0.8 for the X and the D states respectively. The large value for the X state can qualitatively be related to the gerade or ungerade symmetry of the Auger electron.
