All Tables

Table 1: Some relevant energy levels and ionization potentials (in eV) from our MCDF calculations and from NIST (1999) for B-like ions. The energy of each term is obtained as the mean of the energy levels pondered by their statistical weight.
Table 2: Location and designation of the resonances in the photoionization spectrum of N²⁺. The peak numbers refer to Figs. 3 and 4, and * denotes that the initial state of the transition is the 2s2p² ⁴P metastable states - otherwise the initial state is the 2s²2p ²P 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 15 meV.
Table 3: Location and designation of the resonances in the photoionization spectrum of O³⁺. See caption to Table 2. The peak numbers refer to Figs. 3 and 5. The accuracy of the experimental energies listed is about 50 meV.
Table 4: Location and designation of the resonances in the photoionization spectrum of F⁴⁺. See caption to Table 2. The peak numbers refer to Fig. 3. The accuracy of the experimental energies listed is about 200 meV.
Table 5: The measured and calculated oscillator strength (f-values) of the 2s2p² ⁴P $\to$ 2s2pnd ⁴P, ⁴D transitions for N²⁺, O³⁺, and F⁴⁺. Exp: present experimental data; RM: R-matrix calculation by Fernley et al. (1999); MCDF: Multi-Configuration Dirac-Fock calculations performed as part of the present work (N²⁺ and F⁴⁺) or by Champeaux et al. (2003, O³⁺).
Table 6: Some relevant energy levels and ionization potentials (in eV) from our MCDF calculations and from NIST (1999) for Be-like ions. The energy of each term is obtained as the mean of the energy levels weighted statistically.
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.
Table 8: Location and designation of the resonances in the photoionization spectrum of O⁴⁺. See caption to Table 6. The accuracy of the experimental energies listed is about 100 meV.
Table 9: Some relevant energy levels and ionization potentials (in eV) from our MCDF calculations and from NIST (1999) for C-like ions. The energy of each term is obtained as the mean of the energy levels weighted statistically.
Table 10: Location and designation of the resonances in the photoionization spectrum of F³⁺. The peak numbers refer to Figs. 8 and 7. 2s²2p² or 2s2p³ (see Table 9) has been left out of the initial configurations as well as 2s2p² from the final configurations of the transitions. When several terms are given, the MCDF and NIST (1999) energies correspond to the mean values. The accuracy of the experimental energies listed is about 100 meV.
Table 11: Location and designation of the resonances in the photoionization spectrum of Ne⁴⁺. See caption to Table 10. The assignments should be regarded as tentative. The accuracy of the experimental energies listed is about 200 meV.
