Abstract
Calculations for the Stark broadening of H alpha and H beta using a unified theory for both ions and electrons are presented in the density range 1014to 1015cm-3at a temperature of 104K. Although the theory is of marginal validity at these densities, it shows quite conclusively the influence of ion dynamics in reducing the dip at the centre of the H beta profile and the peak in the centre of the H alpha profile.Keywords
