Forbidden emission lines which are or could be observed in hot, low-density astrophysical plasmas are reviewed on the basis of
- astronomical observations
- laboratory measurements
- theoretical atomic structure calculations.
The data are taken from recent literature or extrapolated along isoelectronic sequences when required. Some new theoretical transition probabilities are computed. The ions considered reach their maximum ionization at a temperature higher than 250 000 K and their cosmical abundance is larger than 5 in Ross scale (with log [H] = 12).
The configurations considered are of the types 2s2 2pn, 3s2 3pn, 3s23pk3d where n = 1 to 6 and k = 3 to 5 , 3s3p.
The wavelength range extends roughly from 250 Å to 10 μm. Identifications are discussed along isoelectronic sequences. Some new identifications are proposed. A final finding list gives all wavelengths for the transitions considered and specifies their current status (observed or not).
