Al XIII - VERSION 8.0


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

  1. al_13.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: al_13.elvlc
    %observed 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.
    %comment:    18584144      Limit     
    %comment: theoretical levels are the same as the observed ones.

  3. al_13.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_13.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: al_13.splups
    %oscillator strengths: Wiese,W.L., Smith,M.W., Glennon,B.M., 1966, Atomic Transition Probabilities, NSRDS-NBS-4
    %oscillator strengths: Parpia, F.A., Johnson, W.R., 1982, Phys.Rev.A, 26, 1142
    %collision strengths: interpolation of R-matrix calculations of C VI, Ne X, Si XIV, Ca XX and Fe XXVI
    %comment: the original data used for the interpolation were from the calculations of Aggarwal & Kingston
    (1991 to 1993). The range of temperature for which upsilons were provided was different for each
    ion, however, the interpolated results should be most reliable in the 4.2 < Log T < 6.2.
