3 Tables 1-2

  

Table 1: This table shows electron-, proton-, and He II- impact broadening parameters for Au I, calculated within the full semiclassical perturbation approach (Sahal-Bréchot 1969a,b) for perturber densities of 10¹⁵-10¹⁹ cm^-3 and temperatures from $2\,500$ up to $50\,000$ K. Transitions and averaged wavelengths for the multiplet (in nm) are also given. 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. The asterisk identifies cases for which the collision volume multiplied by the perturber density (the condition for validity of the impact approximation) lies between 0.1 and 0.5. Stark broadening parameters for densities lower than tabulated, are linear with perturber density

Table 2: This table shows electron-impact broadening parameters for Au II, calculated within the modified semiempirical approach (Dimitrijevic & Konjevic 1980; Dimitrijevic & Krsljanin 1986; Popovic & Dimitrijevic 1996) for a perturber density of 10¹⁷ cm^-3 and temperatures from 5000 up to 50000 K. Transitions and averaged wavelengths for the multiplet $(\bar{\lambda}$ in nm) are also given. Stark broadening parameters for other pertuber densities may be obtained by linear scaling, taking into account that for sufficiently higher densities a correction for Debye shielding effect (Griem 1974) should be applied
