Abstract:
Using a semiclassical perturbation approach, we have calculated
electron-, proton-, and He III-impact line widths and shifts for
4 Si XI multiplets for perturber densities 10^18^-10^23^cm^-3^ and
temperatures T=500000-4000000K, and for 61 Si XIII multiplets for
perturber densities 10^16^-10^23^cm^-3^ and temperatures
T=500000-6000000K. For lower perturber densities, obtained results are
linear with perturber density.

Note (1): C/FWHM gives an estimate of the maximum perturber density for which
the line may be treated as isolated and tabulated data may be used
Note (2): FWHM denotes Full Width at Half Maximum
Note (3): A positive (resp. negative) shift is towards the red (resp. blue)
Note (4): An asterisk in this column indicates that 0.1<NV<0.5,
(V=collision volume); beware of the fact that the limit of validity
of the impact approximation is attained for the value that follows
Note (5): Values for NV>0.5 are not given, because in this case the impact
approximation is no longer valid
