Fe XI - VERSION 10.1


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

  1. fe_11.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
     
     Experimental energies:
    Del Zanna, G. 2010, A&A, 514, A41
    Del Zanna, G. 2012, A&A, 546, A97
    
    Theoretical energies:
    Del Zanna, G., Storey, P.J., 2013,  A&A, 549, A42
    
    Note: the theoretical energies are the 'best energies', i.e. 
    are the empirically-adjusted theoretical energies.
    
    Energies for the 3s 3p4 3d levels 54, 67, 79 
    had a tentative assignement. We have revised their energies following the
    tentative identifications in 
    Wang, K., Song, C.X.,Jonsson, P. et al., 2018, ApJSS, 239,30
      doi = {10.3847/1538-4365/aaedba}
    
    Level 102 is left unidentified.

  3. fe_11.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.

     
    
    Theoretical energies, gf and A-values:
    Del Zanna, G., Storey, P.J., 2013,  A&A, 549, A42
    
    Note: the theoretical energies are the 'best energies', i.e. 
    are the empirically-adjusted theoretical energies.
    
    Only transitions with a branching ratio of 10^-5 have been retained.
    
    
     Experimental energies:

    Del Zanna, G. 2012, A&A, 546, A97
