Table 1: This table shows electron-, proton- and Ar II-impact broadening parameters for Ge I for perturber density of 10¹⁶ cm^-3 and temperatures from 2500 up to 50 000 K. Transitions and calculated ( $\lambda$ ) and experimental (in the air - from NIST 2003 - $\lambda _{\rm o}$ ) wavelengths (in Å) are also given in the table. By dividing C by the corresponding full width at half maximum (Dimitrijevic et al. 1991), we obtain an estimate for the maximum perturber density for which the line may be treated as isolated and tabulated data may be used.
