Scientific paper

We present the results of [Ba/Eu] ratio determinations for a sample of Carbon-Enhanced Metal Poor (CEMP) stars, comparing them with other CEMP stars found in the literature for which abundances for both elements are available. The stellar spectra were observed at 4.2m William Herschel Telescope (WHT) on July/2003, using Utrecht Echelle Spectrograph (UES) with R ~ 52000 and S/N ~ 40. WHT covers a wavelength range of λλ3700-5700.
