Table 7: Location and designation of the resonances in the photoionization spectrum of N³⁺. The peak numbers refer to Fig. 6, and * denotes that the initial state of the transition belongs to the 2s2p ³P metastable term - otherwise the initial state is the 2s² ¹S ground state. When several terms are given the MCDF and NIST (1999) energies correspond to the mean value of the terms energy weighted by their statistical population. The accuracy of the experimental energies listed is about 50 meV.
