fe_13d.wgfa (radiative data)

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.

%observed energy levels (16-58): Mendoza, C., Kallman, T.R., Bautista, M.A., Palmeri, P., 2004, A&A, 414, 377
% A values (levels 1- 15): computed from 'superstructure' using a 24 configuration model for Fe XIII.
% A values (levels above ionization): Mendoza, C., Kallman, T.R., Bautista, M.A., Palmeri, P., 2004, A&A, 414, 377
%Autoionization rates: Mendoza, C., Kallman, T.R., Bautista, M.A., Palmeri, P., 2004, A&A, 414, 377
% comment: the superstructure model of Fe XIII included the following configurations:
    3s2 {3p2 3p3d 3d2}
    3s23p {4s 4p 4d 4f}
