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

fe_6.elvlc (energy levels)

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

 
%experimental energy levels: Fuhr, J.R., et al., NIST Atomic Spectra Database, 
              Version 2.0, March 1999, NIST Physical Reference Data
%theoretical energy levels: same as the observed energy levels
%produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration
%
% Enrico Landi 2000
 

fe_6.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.

fe_6.splups (electron collision data)

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.

 

%filename: fe_6.splups
%Oscillator strengths: Chen, G.X., Pradhan, A.K., 2000, A&AS, 147, 111
%effective collision strengths: Chen, G.X., Pradhan, A.K., 1999, A&ASS, 136, 395
%comment: effective collision strengths were provided in the temperature range 4.0 < Log T < 6.0
