The CHIANTI database has the following primary ASCII files for this ion:
contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.
%filename: ar_3.elvlc %Observed energies: Ver. 3.0.3 of the online NIST database. http://physics.nist.gov/PhysRefData/ASD/index.html %Theoretical energies: No theoretical energies available. % produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration % % Peter Young - 3-Jun-2006
contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.
