Calculated X-radiation from optically thin plasmas. V.: Improved atomic data for n = 1 - 2 lines plus satellites from H- and He-like ions, 21 - nl'(n ≥ 2) and 31 - nl' (n ≥ 3) transitions from Fe and Ni ions, and lines from Li to Ne isoelectronic sequences of elements C to Ca. Commentary

The spectral line list in a previously developed computer code has been updated and extended with many new lines up to 300 A. These lines comprise: H- and He-like n = 1 - 2 lines plus their satellites produced by innershell transitions: 2l - nl' (n = 3, 4) transitions in Fe XVII-XXIV (10-17 A) ; 2s - 2p lines in Fe XVIII-XXIII and Ni XX-XXV (90-140 A) ; 3l - nl' (n = 3, 4) transitions in Fe VIII-XVI and Ni X-XIV (50-200 A) and many lines from Li to Ne isoelectronic sequences of elements C to Ca (20-300 A). Intensities of 2131 spectral lines are tabulated over the temperature range 3 × 10 4 - 10 9 K.
