Ar III - VERSION 11.0.1

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

ar_3.elvlc (energy levels)

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

 
%filename: ar_3.elvlc
%Observed energies: Ver. 3.0.3 of the online NIST database. http://physics.nist.gov/PhysRefData/ASD/index.html
%Theoretical energies: No theoretical energies available.

%  Peter Young   -   3-Jun-2006

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: The original upsilons were tabulated over the range 10^3 - 10^5 K. The CHIANTI fits reproduce the data to within 0.28 %.
%Upsilons: Galavis, M.E., Mendoza, C., Zeippen, C.J., 1995, A&AS, 111, 347                                                        
%Theoretical energies: No theoretical energies available - observed energies from .elvlc file used instead.
