1 Introduction

In this paper, we present the second part of a set of spectroscopic orbits of giant barium stars, complementary to the orbits described in a companion paper (Udry et al. 1998, Paper I). The overall sample comes from a systematic survey undertaken in the framework of a collaboration between the Geneva and Bruxelles groups to gain insight into the formation process of barium and Tc-poor S stars. The binary nature of these stars accounts for the observed chemical peculiarities through mass transfer across the system. This sample also allows us to confirm the evolutionary link between barium and Tc-poor S stars. These points are addressed in a companion paper providing the complete analysis of the overall sample (Jorissen et al. 1998).

Other CORAVEL users, around LP in Marseille, also interested in some of the same stars, joined in to permit a better determination of the orbital parameters and thus take the best advantage of the available measurements. The join binary sample is presented here.

As the star sample and the observation characteristics are described in details in Paper I, we will just briefly summarize the main related information in Sect. 2. Section 3 provides the derived radial-velocity curves and orbital elements. Some individual stars are commented as well.
