摘要: Data for the broadening of 24188 Fe II lines by collisions with neutral hydrogen atoms have been computed using theory Anstee & O'Mara as extended to singly ionised species and higher orbital angular momentum states Barklem O'Mara. all between observed energy levels in line lists Kurucz log g f > −5 which is applicable. The variable debt parameter Ep used computing second order perturbation potential chosen be consistent long range dispersion interaction constant C6 -values from Kurucz.
