Abstract

Resonance K auger spectra of molecular oxygen are presented at photon energies corresponding to 1simga --> 1pi(g)(pi*), 3sigma(u)(sigma*), and Rydberg excitations. Atomic-like Auger lines observed in the 3sigma(u)(sigma*) decay spectrum are compared with the pure atomic 1s --> 2p resonance Auger spectrum, and evidence for very fast neutral dissociation is found. The energy shifts of''spectator'' lines in the spectra measured at different excitation energies are discussed and compared with the normal O2 K Auger spectrum.
