Abstract

Wavelengths, statistical weights, and excitation energies for 2031 atomic spectral lines in 658 multiplets whose lower energy levels lie below 2217/cm or 0.275 eV are presented. Transition probabilities and oscillator strengths (f-values) are included for most of the lines, as well as radiation damping constants for many of the stronger ones. The list of resonance lines contains the transitions likely to be observed in absorption in interstellar gas clouds, circumstellar shells, stellar winds, QSO winds, and clouds on the sight lines to QSOs. The tables cover transitions of all the ion stages of all elements from hydrogen to germanium which have permitted or intersystem lines that originate from the ground level or excited fine-structure levels of the ground term at wavelengths longward of the Lyman limit at 911.75 A. Many weak lines are included for the more abundant elements. The best available data on wavelengths and transition probabilities are presented as well as notes indicating where improved information would be most useful.
