H I - VERSION 8.0


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

  1. h_1.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    %filename: h_1.elvlc
    %observed energy levels: Fuhr et al, 1999, NIST Atomic Spectra Database Version 2.0

  3. h_1.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.

    %comment: Wavelengths have been calculated the original energy levels from NIST, that include more
              decimal figures than allowed by CHIANTI format.
