“…The most recent theoretical calculations (e.g., Gu 2003a; Zatsarinny et al 2003;Colgan et al 2003) agree reasonably well with the storage-ring measurements for iron L-shell ions (Savin et al 1999(Savin et al , 2002a. Much less attention has been given to M-shell ions.…”

Dielectronic recombination (DR) rate coefficients for Na-like ions of elements with 12 Z 30 forming Mglike systems are calculated in the independent-process, isolated-resonance approximation. Both Á N ¼ 0 and ÁN > 0 core excitation DR channels are included, as well as the inner-shell excitation channels. Convenient analytic fits are given to the calculated rate coefficients, and comparison is made with the existing theoretical and experimental results.

“…The calculated results of Colgan et al (2003) show a similar shape to our experimental rate coefficients and our AUTOSTRUCTURE results. In the temperatures range of 3 × 10 3 −10 6 K, our AUTOSTRUCTURE calculations agree very well with the rate coefficients of Colgan et al (2003).…”

“…In the temperatures range of 3 × 10 3 −10 6 K, our AUTOSTRUCTURE calculations agree very well with the rate coefficients of Colgan et al (2003). Below 3 × 10 3 , the AUTOSTRUCTURE results show the opposite behaviour to Colgan et al (2003) calculations. The rate coefficients from our AUTOSTRUCTURE calculations have lower values than our experimentally derived results within 25% in the temperature range of 8 × 10 4 −10 6 K. The experimental rate is much higher than the calculated DR rate coefficients in the temperature range of 3 × 10 3 K to 8 × 10 4 K. This enhancement in the experimental plasma rate coefficients is due to high intensity of DR resonances in the energy range of 4 eV to 13 eV compared to the calculations.…”

Recombination spectra of F 5+ producing F 4+ have been investigated with high-energy resolution, using the CRYRING heavy-ion storage ring. The absolute recombination rate coefficients are derived in the centre-of-mass energy range of 0−25 eV. The experimental results are compared with intermediate-coupling AUTOSTRUCTURE calculations for 2s−2p ( n = 0) core excitation and show very good agreement in the resonance energy positions and intensities. Trielectronic recombination with 2s 2 −2p 2 transitions are clearly identified in the spectrum. Contributions from F 5+ ions in an initial metastable state are also considered. The energy-dependent recombination spectra are convoluted with Maxwell-Boltzmann energy distribution in the 10 3 −10 6 K temperature range. The resulting temperature-dependent rate coefficients are compared with theoretical results from the literature. In the 10 3 −10 4 K range, the calculated data significantly underestimates the plasma recombination rate coefficients. Above 8 × 10 4 K, our AUTOSTRUCTURE results and plasma rate coefficients from elsewhere show agreement that is better than 25% with the experimental results.

“…Rate coefficients for ground state dielectronic recombination are taken from Badnell (2006a) for hydrogen-like ions, from Bautista & Badnell (2007) for helium-like ions, from Colgan et al (2004) for lithiumlike ions, from Colgan et al (2003) for the beryllium-like ions, Altun et al (2005) for the boron-like ions, from Zatsarinny et al (2005b) for carbon-like ions, Mitnik & Badnell (2004) for nitrogen-like ions, Zatsarinny et al (2005a) for oxygen-like ions, Zatsarinny et al (2006) for fluorine-like ions, Zatsarinny et al (2004) for neon-like ions, Altun et al (2006) for sodium-like ions, and Altun et al (2007) for magnesium-like ions. This set of calculations provide a coherent set of dielectronic recombination rates and we have adopted them as a standard by which to assess the validity of other calculations.…”

Aims. The goal of the CHIANTI atomic database is to provide a set of atomic data for the interpretation of astrophysical spectra emitted by collisionally dominated, high temperature, optically thin sources. Methods. A complete set of ground level ionization and recombination rate coefficients has been assembled for all atoms and ions of the elements of H through Zn and inserted into the latest version of the CHIANTI database, CHIANTI 6. Ionization rate coefficients are taken from the recent work of Dere (2007, A&A, 466, 771) and recombination rates from a variety of sources in the literature. These new rate coefficients have allowed the calculation of a new set of ionization equilibria and radiative loss rate coefficients.For some ions, such as Fe viii and Fe ix, there are significant differences from previous calculations. In addition, existing atomic parameters have been revised and new atomic parameters inserted into the database. Results. For each ion in the CHIANTI database, elemental abundances, ionization potentials, atomic energy levels, radiative rates, electron and proton collisional rate coefficients, ionization and recombination rate coefficients, and collisional ionization equilibrium populations are provided. In addition, parameters for the calculation of the continuum due to bremsstrahlung, radiative recombination and two-photon decay are provided. A suite of programs written in the Interactive Data Language (IDL) are available to calculate line and continuum emissivities and other properties. All data and programs are freely available at http://wwwsolar.nrl.navy.mil/ chianti
