Abstract
We use the 6-8-12 interatomic potential, with a suitable scaling for the relevant atomic radii, to reproduce the measured broadening and shift of the alkali resonance lines perturbed by noble gases, at temperatures of ∼ 500 K.
Then, using the fit to the data with helium and neon as perturbers, we compute new values for the broadening and shift of the alkali resonance lines due to atomic hydrogen, at the temperature of 5000 K, which are of interest in the analysis of solar and stellar spectra, and discuss the reliability of these results.
