Abstract:
Stark broadening parameters, widths, and shifts for 33 CdI singlets
and 37 triplets were calculated using the semiclassical perturbation
method. The results were compared with available experimental and
theoretical data. Also, regularity in the spectral series
5s2 1S-np 1Po was investigated. The influence of Stark
broadening was analyzed in A-type stellar atmospheres.

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approximation is no longer valid
