Description:
Using a semiclassical approach, we have calculated electron-, proton-,
Mg II-, Si II-, Fe II-, and Ar II- impact line widths and shifts for
267 Mg I multiplets, in order to provide the needed Stark broadening
parameters for all important perturbers for investigation of Solar and
laboratory plasma. An analysis of Solar Rydberg lines in the far
infrared spectrum has been performed as well.

Note (3): A positive (resp. negative) shift is towards the red (resp. blue)
Note (4): An asterisk in this column indicates that 0.1 < N.V < 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 N.V > 0.5 are not given, because in this case the impact
approximation is no longer valid
