N2 - We have measured the total fluorescent intensity and circular polarization of light emitted in 3p4Po→3s4P transitions of excited neutral nitrogen atoms created by the photofragmentation of the N 2 molecule with circularly polarized light having energies between 21 and 26 eV. The intensity measurements show the effect of predissociation of the N 2 Rydberg series R(C) 1Σu+ states by non-Rydberg doubly excited resonances (NRDERs), while nonzero values of circular polarization allow us to unambiguously identify the presence of a directly excited NRDER with 1Π u symmetry in this energy range.
