Description: We have measured the total fluorescent intensity and circular polarization of light emitted in 3p⁴P⁰ → 3s⁴P transitions of excited neutral nitrogen atoms created by the photofragmentation of the N₂ molecule with circularly polarized light having energies between 21 and 26 eV. The intensity measurements show the effect of predissociation of the N₂ Rydberg series R(C)¹Σ_u⁺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.
