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

fe_10.elvlc (energy levels)

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

 
%Observed and Theoretical energies (levels 1-54): Del Zanna, Berrington, Mason, 2004, A&A, 422, 731
%Observed energy levels (55-172): NIST Database for Atomic Spectroscopy, Version 1.0, NIST Standard 
   Reference Database 61, 1995
%theoretical energy levels (55-172): Malinovsky et al., 1980, ApJ, 235, 665
%comment: The second column has the theoretical energies of the  scattering calculations,
   while the third column has the theoretical energies from the SUPERSTRUCTURE calculation 
   (with term energy corrections).

fe_10.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.

%A values and oscillator strengths (levels 1-54): Del Zanna, Berrington, Mason, 2004, A&A, 422, 731
%comment: Theoretical wavelengths for levels 1-54 are obtained from the SUPERSTRUCTURE calculation
   (with term energy corrections) in the .elvlc file, from Del Zanna, Berrington, Mason, 2004, A&A, 422, 731
%A values (levels 55-172): A SSTRUCT run performed by P.R.Young.
%comment: the A values for transitions between levels 55-172 have been calculated using a
    configuration model of Fe X in SSTRUCT. The configurations included were:

    3s2 3p5,  3s 3p6,  3s2 3p4 3d,  3s 3p5 3d,  3p6 3d
    3s2 3p3 3d2,  3s 3p4 3d2
    3s2 3p4 4s,  3s2 3p4 4p,  3s2 3p4 4d
    3s2 3p4 4f,  3s2 3p4 5s,  3s2 3p4 5p
    3s 3p5 4s,   3s 3p5 4p,   3s 3p5 5s

fe_10.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_10.splups
%Oscillator strengths (levels 1-54): Del Zanna,  Berrington, Mason, 2004, A&A, 422, 731 (scattering calculation)
%Collision data for transitions to the first three levels: Pelan, Berrington, A&A 2001, 365, 258
%Collision data for transitions to levels up to 54: Del Zanna,  Berrington, Mason, 2004, A&A, 422, 731
%collision strengths for transitions to levels 55-172: Malinovsky et al., ApJ 235, 665, 1980
%comment: Maxwellian-averaged collision strengths have been calculated in the temperature range 2.5 10^5 - 10^7 K
%comment:      Although for many of the transitions involving levels >62 there
     were gf values available, they have been fitted as Type 2
     transitions. This is because, as Type 1 transitions they were often
     difficult to fit (the 1-89 transition is a typical example).

     Some of the 4s transitions (levels 55-62) showed unusual shapes
     in the omega structure (e.g., 2-56, 1-58). I'm not sure how
     trustworthy this data is.

fe_10.psplups (proton collision data)

contains the spline fits to the scaled proton collision strengths.

 

%filename: fe_10.psplups
%rates: Bhatia A.K., Doschek, G.A., ADNDT 60, 97, 1995
%rates: Bely O., Faucher P., A&A 6, 88, 1970 (for 1-2 transition)
%energies: Observed energies from .elvlc file, except for level 10 for which 
    the theoretical energy from the .elvlc file is used.
%comment: For all transitions except 1 - 2, the rates were only tabulated at 
    one temperature. I have fit this data with a straight line that is 
    forced to be zero at a scaled temperature of 0 to emulate the 
    behaviour of proton rates.
%comment: Fitted using single_temp.pro with scalx=0.90
