K XII - VERSION 10.1


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

  1. k_12.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: k_12.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 - Apr 2003
     
    

  3. k_12.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.

    %filename: k_12.wgfa
    %observed energy levels: Edlen, B., 1983, Phys. Scr., 28, 51
    %Radiative data allowed transitions: Landi, E. 2005, A&A, 434, 365
    %Radiative data transition within the ground configuration: Tachiev, G.I., Froese Fischer, C., 2002, A&A. 385, 716
    %Radiative data 3-4 and 4-5 transitions: Froese Fischer, C., Saha, H.P., 1983, Phys. Rev. A., 28, 3169
    % Comment: A values for transitions 3-4 and 4-5 have been corrected to account for observed level energies.
