ATOMIC DATA FOR PERMITTED RESONANCE LINES OF ATOMS AND IONS FROM H TOSI, AND S, AR, CA, AND FE

We list vacuum wavelengths, energy levels, statistical weights, transi tion probabilities, and oscillator strengths for permitted resonance s pectral lines of all ions of 18 astrophysically important elements (H through Si, S, Ar, Ca, Fe). Using a compilation of experimental energy levels, we derived accurate wavelengths for 5599 lines of 1828 ground -term multiplets which have gf-values calculated in the Opacity Projec t. We recalculated the Opacity Project multiplet gf-values to oscillat or strengths and transition probabilities of individual lines. For com pleteness, we added 372 resonance lines of Ne I, Ar I, Fe I, and Fe II ions which are not covered by the Opacity Project. Intercombination a nd forbidden lines are not included in the present compilation. (C) 19 96 Academic Press, Inc.
