Scientific paper

We present spectrophotometry of a sample of 26 Southern binary galaxies 17 pairs were confirmed to be physically associated with typical separation of 136 h^{-1} kpc. Pairs with velocity difference Delta v >= 600 km s^{-1} are probably not physically bound. A comparison with field galaxies suggests that galaxies in pairs tend to have a younger population probably stimulated by tidal interaction. No correlation between the young population and projected separation was found.
