Ne VI - VERSION 10.1


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

  1. ne_6.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
     
    Experimental energies:
    Kramida, A., Ralchenko, Yu., Reader, J., and NIST ASD Team (2013).

       DOI: 10.1051/0004-6361/201220277
    
    Note: in the previous v.8 file levels 6,7
    an 12, 13  were inverted.

      Removed level 204 (2s 2p 4f 2D3/2) as the collision strengths for this levels
      are all zero.
    
     -1
     
    

  3. ne_6.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.

    Note: the previous v.8 file had incorrect values for the 
    transitions from levels 6,7 which were inverted. 
    
    Note: only transitions with a branching ratio above 10^-5 
    have been retained.
