S VII - VERSION 11.0.1

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

s_7.elvlc (energy levels)

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

 
 
Observed energies: 
Mostly from 
Jupen C. and Engstrom L., 2002, Physica Scripta, 66, 140

Those for levels 6,69, 93, 113, 143,147,177 
are from Kramida, A., Ralchenko, Yu., Reader, J., and NIST ASD Team (2012). 
NIST Atomic Spectra Database (ver. 5.0), [Online]. Available: http://physics.nist.gov/
  
Theoretical energies: 
 Liang, G. Y. & Badnell, N. R. 2010, A&A, 518, A64
 doi = {10.1051/0004-6361/201014170}
 adsurl = {http://adsabs.harvard.edu/abs/2010A%26A...518A..64L}

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.
