We report results of the Stark broadening calculations for Sr+ and Ba+ resonance lines in ultra-
cold plasmas using semiempirical formulas and numerical computer simulation technique. The simulation
results show that strong collisions dominate Stark broadening at very low electron temperatures and weak
collision approximation used recently by Vrinceanu et al. cannot be applied in this temperature region.
Consequently, the temperature trend of Stark widths and shifts changes from 1/ T successfully used at
elevated temperatures to an increasing trend with temperature, which is characteristic for strong collisions
at low temperature.
