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.
Experimental energies: Kramida, A., Ralchenko, Yu., Reader, J., and NIST ASD Team (2013). NIST Atomic Spectra Database (ver. 5.1), see http://physics.nist.gov/asd Theoretical energies: G Y Liang, N R Badnell and G Zhao A&A 547, A87 (2012) DOI: 10.1051/0004-6361/201220277 Note: in the previous v.8 file levels 6,7 an 12, 13 were inverted. Produced for the CHIANTI database by G. Del Zanna 7 August 2017 % 23-Oct-2020, Peter Young Removed level 204 (2s 2p 4f 2D3/2) as the collision strengths for this levels are all zero. -1
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.
