Na VI - VERSION 8.0


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

  1. na_6.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: na_6.elvlc
    %observed energy levels: Edlen, B., Phys. Scr. 1985, 31, 345
    %theoretical energy levels: Zhang, Sampson, ADNDT, 1996, 63, 275
    %produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration
    %
    % Enrico Landi 1997
     
    

  3. na_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.

     
    %filename: na_6.wgfa
    %observed energy levels: Edlen, B., Phys. Scr. 1985, 31, 345
    %Allowed transitions oscillator strengths: Zhang, Sampson, ADNDT, 1996, 63, 275
    %Transitions between the ground levels: Galavis etal, 1997, A&ASS, 123, 159
    %Intercombination transitions: interpolated from the trans. prob of Ne V, Mg VII, Si IX, S XI
    %A-values (2-4 and 3-4 transitions): Storey PJ, Zeippen CJ, MNRAS 312, 813, 2000

  5. na_6.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: na_6.splups
    %oscillator strengths: Zhang, Sampson, 1996, ADNDT, 63, 275
    %collision strengths: Zhang, Sampson, 1996, ADNDT, 63, 275
    %effective collision strengths ground transitions: Burke, V.M., Lennon, D.J., 1994, A&ASS, 103, 273
    %comment: effective collision strengths were provided in the temperature range 3.0 < Log T < 5.0
