Abstract: We present a spectroscopic study of the delta Scuti star 20 CVn. The spectra were obtained at the Observatoire de Haute Provence with the new echelle spectrograph ELODIE. Using the correlation configuration of the instrument, an extremely precise (< 0.05 km.s(-1)) velocity curve has been derived. The velocity variations are sinusoidal and a fit to the data provides a peak-to-peak amplitude 2K = 1.244 +/- 0.016 km.s(-1).
