A previously developed extension of the quasistatic approximation which allows for the broadening of hydrogen lines by low-frequency fields is applied to the first four Lyman lines of hydrogen, ionized helium, C VI, and Ar XVIII. It is demonstrated numerically that the low-frequency Stark broadening is Gaussian in the case of relatively small dynamical corrections. Extrapolation of this Gaussian approximation to cases with large corrections leads to good agreement with measurements of the Lyman-..cap alpha.., -..beta.., and -..gamma.. lines of hydrogen and allows the prediction that the Lyman-delta should retain its central dip.
