Fe IX - VERSION 8.0


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

  1. fe_9.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    
    Observed and theoretical energies: 
    
    Del Zanna, G., Storey, P. J., Badnell, N. R., Mason, H. E., 2014, A&A, 565, A77
    DOI: 10.1051/0004-6361/201323297
    
    Note: the the theoretical energies are the 'best energies', i.e. 
    are the empirically-adjusted theoretical energies.
    
    
    Theoretical energy levels (n=6 levels above level no.865):
    O'Dwyer, B., Del Zanna, G., Badnell, N.R., Mason, H. E.,Storey, P.J.,

  3. fe_9.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:

    are the empirically-adjusted theoretical energies.
    
    n=6 levels (above level no.865):
