Abstract:
    By using the semiclassical-perturbation formalism, we have calculated
    electron-, proton-, and He III-impact line widths and shifts for
    4 K VIII and 30 K IX multiplets, of interest for analysis,
    investigation and modeling of different plasmas in solar and stellar
    subphotospheric layers research and plasma physics. The obtained
    results are presented as a function of temperature and perturber
    density. Results are compared with other theoretical estimates, based
    on regularities and systematic trends.

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           approximation is no longer valid
