The CHIANTI database consists of 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.
%energy levels: Shirai,T., Sugar,J., Musgrove,A., Wiese,W.L., 2000, J.Phys.Chem.Ref.Data, Monograph 8
%energy levels 30, 32: Bhatia, A.K., Doschek, G.A., 1992, ADNDT, 52, 1
%energy levels 28, 37: Kelly, R. L., 1987, J. Phys. Chem. Ref. Data 16, Suppl. 1
%theoretical energy levels (n=3): Bhatia, A.K., Doschek, G.A., 1992, ADNDT, 52, 1
%theoretical energy levels (n=4): Zhang, H.L., Sampson, D.H., 1989, ADNDT, 43, 1
% Note: some energy levels from the NIST database, version 2.0, have been renumbered
in order to match the identification given by Bhatia and Doschek
and their theoretical energy levels. In particular, the following changes
have been made:
NIST --> CHIANTI
12 --> 9
13 --> 12
9 --> 13
25 --> 21

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.

contains the spline fits to the electron collision strengths scaled according the rules formulated by Burgess and Tully (1992). Accurate replication of the temperature averaged collision strength over a wide range of temperatures can be accomplished with the data in this file.
