Scientific paper

New observations are reported for the discordant redshift pairs 4030-11 and 4151-46. Both direct and spectroscopic evidence is advanced that the galaxies in each pair are interacting. Direct evidence consists of luminous connections and perturbations particularly in the higher redshift components of each pair. Spectroscopically one observes an asymmetric distribution of Hα emission in both lower redshift components. The low-redshift Hα emission in both pairs is observed to extend from the low-redshift galaxy into the high-redshift companion. In addition an unusual double component Hα emission line is observed in one of the high-redshift galaxies, 4030-11.
