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.
