Interference quenching of nu('')=1 vibrational line in resonant photoemission of N-2: A possibility to obtain geometrical information on the core-excited state
An interference quenching of the nu"=1 vibrational line in the resonant Auger decay of N 1s-->pi(*) core-excited N-2 is observed and analyzed. The intensity ratio between the nu"=1 and nu"=0 vibrational levels of the X(2)Sigma(g)(+) final state shows a surprising nonmonotonous variation as a function of frequency detuning, going through a minimum with a complete suppression of nu"=1. We have devel
