摘要：Y, Zr, Ba, La, Ce, Nd , Sm and Eu abundances are found for 172 of FGK dwarfs belonging to thin and thick disks of the Galaxy (-1.0 <[Fe/H] < 0.3). The studied stars were observed at high resolution, high signal to noise ratio with the ELODIE echelle spectrograph at the Observatoire de Haute-Provence (France). Effective temperatures Teff were estimated by the line depth ratio method and from the Ha line-wing fitting. Surface gravities log g were determined by two methods : parallaxes and ionization balance of iron. The selection of stars was made on kinematic criterion. The relative contributions of s- and r-procesess were evaluated and interpreted through theoretical computations of the chemical evolution of the Galaxy. The considered model reproduces quite well the trend of Sm and Eu with metallicity.
