Scientific paper

Ba II line equivalent widths appear to be well correlated with the
absolute magnitudes for yellow supergiants. Two Ba II lines 5853.6
Angstroms and 6141.7 Angstroms were applied for investigation of the
possible relation between their equivalent widths and Mv for
small-amplitude Cepheids and non-variable supergiants.
