J/A+A/533/A87       Sulphur ions iso-electronic sequence     (Liang+, 2011)

R-matrix electron-impact excitation data for astrophysically abundant sulphur ions. Liang G.Y., Badnell N.R., Zhao G., Zhong J.Y., Wang F.L. <Astron. Astrophys. 533, A87 (2011)> =2011A&A...533A..87L
ADC_Keywords: Atomic physics Keywords: plasmas - atomic processes - atomic data Abstract: We present our calculated data including energy levels, radiative decay rates and effective collision strengths for all the transitions among fine-structure levels of n=3 or 4 configurations, for four iso-nuclear ions, viz S8+, S9+, S10+ and S11+. Description: The effective collision strengths at 13 temperatures ranging from 2x102(q+1)2 to 2x106(q+1)2K, where q is the residual charge of ions, have been calculated using the ICFT R-matrix method. The data format adopts ADAS adf04 format, see the file at website http://www.adas.ac.uk/man/appxa-04.pdf Additionally, tables of level energies for S^10+ and S^11+, along with other predictions are available in this online material.
