Ca XIII - VERSION 8.0


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

  1. ca_13.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: ca_13.elvlc
    %Observed energy levels (1 - 10): Edlen, 1983, Ph. Scr., 28, 51
    %Observed energy levels (4,5): Feldman, Curdt, Landi, Wilhelm, 2000, ApJ, 544, 508
    %Observed energy levels (11): from the spectrum of Acton et al 1985, ApJ, 291, 865
    %Observed energy levels (12 - 16,25 - 26): Doschek et al 1973, J.Opt.Soc.Am, 63, 1463
    %Observed energy levels (2s2.2p3.3d configuration): Fawcett & Hayes, 1975, MNRAS, 170, 185
    %theoretical energy levels: Landi, E., Bhatia, A.K., 2005, A&A, 444, 305
    %comment: theoretical energy levels come from the 24-configuration calculation in Landi & Bhatia (2005)

  3. ca_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. ca_13.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: ca_13.splups

    %Oscillator strengths: Landi & Bhatia 2005, A&A, 444, 305
    %comment: oscillator strengths have been taken from the 6-configuration model of Landi & Bhatia
    (2005) for consistency with the collisional calculation
