The CHIANTI database consists of the following primary ASCII files for this ion:

fe_22.elvlc (energy levels)

contains the energy levels in cm^(-1) It includes both experimental and theoretical values of the levels energies.

 
%experimental energy levels: Shirai,T., Sugar,J., Musgrove,A., Wiese,W.L.,2000, J.Phys.Chem.Ref.Data, Monograph 8
%experimental energy levels (levels 17,18): Kelly, R. L., 1987, J. Phys. Chem. Ref. Data 16, Suppl. 1
%theoretical energy levels: Badnell, N.R., Griffin, D.C., 2002, J.Ph.B, in press
%Comment:
 1 - The observed energies for levels 174 (2s2p(3P).4d 2F7/2) and 195 (2s2p(1P).4d 2F7/2) have been 
     interchanged to match theoretical energies
 2 - The observed energies for levels 32 (2s2p(3P).3p 4S3/2) and 35 (2s2p(3P).3p 2D3/2) have been 
     interchanged to match theoretical energies
 2 - The observed energies for levels 24 (2s2p(3P).3s 2P1/2) and 29 (2s2p(3P).3p 2P1/2) have been 
     interchanged to match theoretical energies

fe_22.wgfa (radiative data)

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.
