- Table 1:
Stark broadening parameters for Sii
spectral lines.
This table shows electron-, proton-, and ionized
helium-impact
broadening parameters for Sii for a perturber density of 1014 cm-3 and temperatures from 2500 up to 50 000 K. The quantity C (given in Å cm-3),
when divided by the corresponding full width at half maximum,
gives an estimate for the maximum perturber density for which
tabulated data may be used. The asterisk identifies cases for which the
collision volume multiplied by the perturber density (the condition for
validity of the impact approximation) lies beetwen 0.1 and 0.5. For higher
densities,
the isolated line approximation used in the calculations breaks down.
FWHM(Å) denotes full line width at half maximum in Å, while SHIFT(Å)
denotes line shift in Å.

for Stark widths and shifts.
