Al X - VERSION 8.0


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

  1. al_10.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: al_10.elvlc
    %energy levels:  Martin, W. C., Sugar, J., Musgrove, A., and Dalton, G. R., 1995, 
      NIST Database for Atomic Spectroscopy, Version 1.0, NIST Standard Reference Database 61.
    %Theoretical energy levels: Zhang, Sampson, ADNDT, 1992 , 52, 143
    %produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration
    %
    % E. Landi and K.P.Dere 1995
     
    

  3. al_10.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.

    %Allowed transitions oscillator strengths: Zhang, Sampson, ADNDT, 1992 , 52, 143
    %comment: transitions 1-4, 3-4, 3-10 have been interpolated from
        the data of Be-like ions in Muhlethaler, Nussbaumer, A&A, 1976, 48, 109

  5. al_10.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: al_10.splups
    %Effective collision strengths: Keenan et al., 1986, Physica Scripta 34, 216
    %Allowed transitions oscillator strengths: Zhang, Sampson, ADNDT, 1992 , 52, 143
    %comment: Have derived the upsilon data from Table V of Keenan et al.
    The Delta-E's have been taken from the observed values in the .elvlc
    file. The gf values are from the .wgfa file.
    The upsilons have been created for logT=6.1+-0.8 in 0.1 dex intervals.
