Data for the broadening of 24188 Fe II lines by collisions with neutral hydrogen atoms have been computed using the theory of Anstee & O'Mara (1991MNRAS.253..549A, 1995MNRAS.276..859A) as extended to singly ionised species and higher orbital angular momentum states by Barklem & O'Mara (1998MNRAS.300..863B). Data have been computed for all Fe II lines between observed energy levels in the line lists of Kurucz with loggf>-5 for which the theory is applicable. The variable energy debt parameter E_p used in computing the second order perturbation theory potential is chosen to be consistent with the long range dispersion interaction constant C₆ computed using the f-values from Kurucz.
