Description:
Using a semiclassical approach, we have calculated electron-, proton-,
and ionized helium-impact line widths and shifts for 33 Sr I
multiplets for perturber densities 10^13^cm^-3^ (for stellar plasma
research) and 10^15^-10^18^cm^-3^ (for laboratory plasma research) and
temperatures T=2500-50000K.

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approximation is no longer valid
