Radial velocity measurements of classical Cepheids obtained by
the CORAVEL and ELODIE spectrographs have been analysed. The
comparison with earlier radial velocity data resulted in the
discovery of eight new spectroscopic binaries (in the 9
7-12
4
interval of mean V-brightness). An updated value of the pulsation period
is also determined for the new SB-Cepheids.
Key words: Cepheids / binaries: spectroscopic
