Ar XVI d - VERSION 8.0


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

  1. ar_16d.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: ar_16d.elvlc
    %observed energy levels (1 - 24): Kelly, R.L., 1987, J.Phys.Chem.Ref.Data 16, Suppl. 1
    %Theoretical energy levels (1 - 24): Zhang, H.L.,Sampson, D.H.,Fontes, C.J., 1990, ADNDT, 44, 31
    %energy levels (above IP): Vainshtein, L.A., Safronova, U.I., 1978, ADNDT, 21, 49
       and 1980, ADNDT, 25, 311 - updated by U.I. Safronova, 1999

  3. ar_16d.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: ar_16d.wgfa
    %observed energy levels: Kelly, R.L., 1987, J.Phys.Chem.Ref.Data 16, Suppl. 1
    %observed energy levels (level 25): NIST, version 2
    %theoretical energy levels: Zhang, H.L., Sampson, D.H., Fontes, C.J., 1990, ADNDT, 44, 31
    %oscillator strengths: Zhang, H.L., Sampson, D.H., Fontes, C.J., 1990, ADNDT, 44, 31
    %oscillator strengths: Martin, I., Karwowski, J., Diercksen, G.H.F., Barrientos, C., 1993, A&AS, 100, 595
    %A values (above IP): Vainshtein, L.A., Safronova, U.I., 1978, ADNDT, 21, 49
       and 1980, ADNDT, 25, 311 - updated by U.I. Safronova, 1999
    %comment: theoretical energies have been used as experimental values for the dielectronic transitions

  5. ar_16d.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

     
    %filename: ar_16d.splups
    %collision strengths: from updated autoionization rates of Vainshtein, L.A., Safronova, U.I., 1978, ADNDT, 21, 49
    and 1980, ADNDT, 25, 311 - updated by U.I. Safronova, 1999
