Abstract:
High-resolution spectroscopic observations are presented for 19
single-lined binaries (giants and dwarfs) with orbital elements and
mass functions similar to those of barium stars, two radial velocity
non-variable barium stars, and two standards. All binary systems
contain an unseen low-mass component, presumably, a white dwarf.
The equivalent widths and oscillator strengths are given for all
measured spectral lines.
