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

ne_3.elvlc (energy levels)

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

 
%observed energy levels: Fuhr, J.R., et al., 1999, "NIST Atomic Spectra Database" ver. 2.0
     March 1999. NIST Physical Reference Data
%theoretical energy levels: Bhatia & Landi, 2005, ADNDT, 89, 139
comment: the NIST energy of level 2s2.2p3(2D).3p 3P2 has been associated to level 2s2.2p3(2D)3p 1D2

ne_3.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: Fuhr, J.R., et al., 1999, "NIST Atomic Spectra Database" ver. 2.0

%theoretical energy levels: Bhatia & Landi, 2005, ADNDT, 89, 139
%A-values (transitions 2-5, 4-5): Daw A., Parkinson W.H., Smith P.L., Calamai A.G., 2000, ApJ, 533, 179
%A values and oscillator strengths: Bhatia & Landi, 2005, ADNDT, 89, 139
%comment: The A-values from Daw et al. are experimentally determined and have
    accuracies of +/- 9% (2-5) and +/- 7% (4-5)

ne_3.splups (electron collision data)

contains the spline fits to the electron collision strengths scaled according the rules formulated by Burgess and Tully (1992). Accurate replication of the temperature averaged collision strength over a wide range of temperatures can be accomplished with the data in this file.

 

%filename: ne_3.splups
%oscillator strengths: Landi & Bhatia 2005, ADNDT, 89, 139
%effective collision strengths within the ground configuration: McLaughlin B.M., Bell K.L., 2000, J.Phys.B, 33, 597
%Collision strengths: Landi & Bhatia 2005, ADNDT, 89, 139
%comment: effective collision strengths are provided in the temperature range 3.0 < Log T < 6.0
