Na X - VERSION 8.0


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

  1. na_10.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

    %experimental energy level (5): Curdt, W., Landi, E., Wilhelm, K., Feldman, U. 2000, Phys. Rev. A, 62, 022502
    %theoretical energy levels: Aggarwal, K.M., Keenan, F.P., Heeter, R.F. 2009, Phys. Scr., 80, 045301
    %comment: the energy of level 5 has been obtained using the wavelength from Curdt et al 2000 and 
        the NIST energy for level 2
    %comment: theoretical levels were taken from the FAC1 dataset of Aggarwal et al 2009

  3. na_10.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.
