Scientific paper

Tables of Stark broadening for He II lines of the Balmer, Paschen and Pickering series under conditions of astrophysical interest have been generated. They are based on the Unified Theory as developed by Vidal et al. (1970) but including the effects of the ionic charge on the paths of the electrons. The implications for high resolution spectroscopy of central stars of planetary nebulae involving the improved broadening theory are discussed.
