Al VI - VERSION 8.0


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

  1. al_6.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: al_6.elvlc
    %experimental energy levels: Edlen, B., 1983, Phys. Scr., 28, 51
    %theoretical energy levels: Landi, E., 2005, A&A, 434, 365
    % produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration
    % 
    % E. Landi - May 2004
     -1
     
    

  3. al_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.

  5. al_6.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: al_6.splups
    %effective collision strengths: interpolated using Ne III, Mg V, Si VII, S IX, Ar XI, Ca XIII
    %comment: data are most accurate in the 3.0 < Log T < 5.0 temperature range.
    %comment: interpolated data were preferred over Close Coupling calculations from
    %         Butler & Zeippen, 1994, AASS, 108, 1 for transitions within the ground
    %         configuration since, as noted by the authors themselves, their Al VI upsilons
    %         were uncertain due to the presence of resonances close to threshold, which
    %         their model was not able to adequately describe.
