The N2 1sB 2 Xd dispersed fluorescence from photon excited N2 molecules has been measured in the 19–34 eV excitation range, where our theory predicts the existence of non-Rydberg doubly excited resonances which autoionize in the sub-fs regime into the N2 1 B2S1u ionic state. The experimentally deduced vibrational branching ratios sy0 1dysy0 0d revealed five prominent features, four of which could be identified as such doubly excited resonances based on the lowest order of the many-body perturbation theory.
