S XIII - VERSION 10.0.2


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

  1. s_13.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
     
      Theoretical energies:
    Fernandez-Menchero, Del Zanna and Badnell, A&A, 2014, 566, A104
    doi = {10.1051/0004-6361/201423864}
    
    Note: only the bound levels up to n=5 have been retained. 
    
     Observed energies:
    
    n=2 levels: NIST database
    Other levels:
    Fawcett & Hayes 1987, Phys. Scr., 36, 80
    Goldsmith, S., Oren, L., Cohen, L., 1974, ApJ, 188, 197
    
    Levels 11,13,15: Fawcett and Hayes.
    Levels 17,18,19,20,25 Fawcett and Hayes. Note: level 20, 2s 3d 1D2 had an incorrect
    energy in the previous CHIANTI version.
    Level 27, 2p 3p 3D2: from energy difference in Goldsmith et al., not reported by NIST
    Levels 28,29,31,32,37 Fawcett and Hayes
    Level 38, 2p 3d 3D1 Goldsmith et al.
    Levels 39,40,41,44  Fawcett and Hayes
    Level 45 2p 3d 1F3  Fawcett and Hayes, not reported by NIST
    Level 46 Fawcett and Hayes
    Levels 52,54,55,56     Fawcett and Hayes
    Level 69 2p 4p 3D3  Fawcett and Hayes, not reported by NIST, not in
          previous CHIANTI version
    Level 83  Fawcett and Hayes

  3. s_13.wgfa (radiative data)
  4. 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.

     
    
    gf-values, A-values and theoretical energies:
    Fernandez-Menchero, Del Zanna and Badnell, A&A, 2014, 566, A104
    doi = {10.1051/0004-6361/201423864}
    Only transition probabilities with a branching ratio
    greater than 10^(-5) have been retained.
    
    
    gf-values, A-values for the n=2,3 (lowest 20 levels):
