A list of data for the broadening of metallic lines by neutral hydrogen collisions

A list of data for the broadening by neutral hydrogen collisions of many as trophysically important spectral lines, which has been incorporated into th e Vienna Atomic Line Database (VALD), is presented. Data for lines of neutr al atoms are interpolated from the tabulated data of Anstee & O'Mara (1995) , Barklem & O'Mara (1997), and Barklem et al. (1998). Data for lines of sin gly ionised atoms are compiled from the calculations by Barklem & O'Mara (1 998, 2000), The list at present contains data for 4891 lines between 2300 a nd 13000 Angstrom of elements from Li to Ni. We examine the statistical imp act of the new theory by comparison with the previously available data. We also demonstrate the direct effect on spectral synthesis calculations.
