Resonances in Core-Level Shake-off Spectra of CO and N2 Adsorbed on Ni(100): Implications for Photonen that several ion thresholds are considerably delayed compared to the core ionization thresholds. For this reason it has been proposed that the fragmentation of molecular adsorbates are mainly-related to multiple electron excitations such as shake-up and shake-off processes.
