| Abstract: | Radiative lifetimes were determined for two short-lived states in neutral nitrogen. Following photo-dissociation and two-photon excitation employing the same UV source, excitation to higher states was performed with a distributed feedback dye laser (DFDL). The lifetimes were found to be τ(2p 24d 4 D 7/2)=17(3) ns and τ(2p 25s 4 P 5/2)=22(3) ns. |
