Fe XIV - VERSION 8.0


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

  1. fe_14.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: fe_14.elvlc
    %Observed energies (1-197): reassessed from original measurements -- see comments below
    %Observed energies (122, 125, 136): Del Zanna 2012, A&A, in press
    %Theoretical energy levels (1-197): Liang et al. 2010, ApJS, 190, 322
    %Theoretical energy levels (198-739): Landi & Dere 2012. ADNDT, submitted
    %Comment: the wavelengths from  Churilov,S.S. Levashov,V.E., 1993 Physica Scripta 48, 425  
              were adopted for most transitions. A few added wavelengths are from

  3. fe_14.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. fe_14.scups (electron collision data)
  6. contains the effective electron collision strengths scaled according to the rules formulated by Burgess and Tully (1992).

    %Oscillator strengths (levels 1-197): Liang et al. 2010, ApJS, 190, 322

    %Collision strengths (levels 198-739): Landi & Dere, 2012, ADNDT, submitted
    %comment: The Liang et al. (2010) were fitted with 9-point splines, however the structure of
    the data was such that only the data between 10$^5$ and 10$^7$ K could be fitted.
