Appendix: Atomic data for the blended dielectronic satellite lines with n=2, 3, 4

We report in this Appendix the atomic data related to the dielectronic satellite lines, calculated in this work for Z=10, 12, and 14, blended with one of their parent lines: forbidden, intercombination, and resonance.

The satellite line wavelengths and intensities have been obtained using a set of computer codes developed partly in University-College-London (SUPERSTRUCTURE: Eissner, Jones, Nussbaumer 1974) and in Meudon Observatory (AUTOLSJ: TFR group, Dubau J., Loulergue M. 1981). Multiconfigurational-wavefunctions are calculated in a "scaled" Thomas-Fermi-Dirac-Amaldi potentials, depending on linear scaling parameters ( $\lambda_{\rm s}$,  $\lambda_{\rm p}$,  $\lambda_{\rm d}$...) different for l-orbitals, which are obtained through a self-consistent variational procedure on the energy sum of the first lowest (SL) terms. In SUPERSTRUCTURE, the level energies and the radiative probabilities are calculated in the relativistic Breit-Paul hamiltonian approach, which gives fine-structure bound and autoionizing levels. In the AUTOLSJ code, the autoionization probabilities are derived in the Distorted-wave approximation, using the same wavefunctions as in SUPERSTRUCTURE. For the present calculations, the following configuration were used: $1{\rm s}^2nl$, $1{\rm s2s}nl$, and $1{\rm s2p}nl$ for $n = 2,\cdots,5$ and $0\le l \le n-1$.

The wavelengths of the dielectronic satellite lines calculated here should be compared to the "reference'' wavelengths used in the Jacques Dubau's calculations respectively for Ne IX, Mg XI, and Si XIII, $\lambda_{w}=13.4658$, 9.1740, 6.6482 Å, $\lambda_{y}=13.5774$, 9.2395, 6.6903 Å, $\lambda_{x}=13.5774$, 9.2358, 6.6865 Å, $\lambda_{z}=13.7216$, 9.3219, 6.7420 Å. One can notice that these wavelengths are not identical to the wavelengths of Vainshtein & Safronova (1978) used in the calculation of the line ratios R and G, tabulated in Table 1. Then in order to determine which dielectronic satellite lines are blended with one of the parent lines (forbidden, intercombination, and resonance), one should take into account the shift of the satellite line compared to the wavelengths chosen for the parent lines in the calculation of R and G.

The values of $E_{\rm s}$, which is the energy of the satellite level s, used in this calculation are well reproduced using formula (29).

In Tables A.1, A.2, and A.3, the dielectronic satellite lines n=2, for Z=10, 12, and 14, respectively are reported. In Tables A.4, A.5, and A.6, the dielectronic satellite lines n=3, and 4, for Z=10, 12, and 14, respectively are reported.
