Ne IV - VERSION 8.0


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

  1. ne_4.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: ne_4.elvlc         
    %observed energy levels: Kramida, A. E., Bastin, T., Biemont, E., Dumont, P.-D. & Garnir, H.-P.
                             Eur. Phys. J. D, 7, 525, 1999                      
    %theoretical energy levels: C.A. Ramsbottom (private communication)
    % produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration

  3. ne_4.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.

    %A-values (levels 1 to 5): Merkelis, G., Martinson, I., Kisielius, R. & Vilkas, M.J. 1999, Phys. Scripta, 59, 122
    %A-values: from a SSTRUCT model
    %comment: the following configurations were input to SSTRUCT:

  5. ne_4.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).
