Bond-distance-dependent decay probability of the N 1s→π* core-excited state in N2
We report the observation of the unusually weak decay of the N 1s→π* core-excited N2 molecule to the B 2Σu+ final state of N2+, which is only detectable in an experiment with high sensitivity. The resonant Auger spectra exhibit an unexpected dependence on the selected vibrational level of the intermediate state. Theoretical calculations show that the interference between direct and resonant photoe
