Ca VII - VERSION 8.0


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

  1. ca_7.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

    %observed energy level 18: Kelly, R.L., 1987, J.Phys.Chem.Ref.Data, 16, Suppl.1
    %Theoretical energy levels: Landi & Bhatia, 2003, ApJ, 589, 1075
    %Comment: Theoretical energies are taken from the 25-configuration model of Landi & Bhatia 2003.

  3. ca_7.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_7.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: ca_7.splups
    %oscillator strengths: Landi & Bhatia 2003, ApJ, 589, 1075
    %collision strengths: Landi & Bhatia 2003, ApJ, 589, 1075
    %comment: oscillator strengths are from the 5-configuration models in Landi & Bhatia 2003,
    for consistency with the atomic model in the collision problem
