Abstract:
The electron - impact line widths and shifts for 16 Mn II, 3 Mn III,
10 Ga III, 8 Ge III and 14 Ge IV multiplets, have been considered
within a modified semiempirical approach. Moreover, using a
semiclassical approach, we have considered electron-, proton-, and He
III-impact line widths and shifts for 3 Ge IV multiplets. The obtained
results have been compared with other theoretical results.

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approximation is no longer valid
