We present spectroscopy of the eclipsing recurrent nova U Sco. The radial velocity semi-amplitude of the primary star was found to be from the motion of the wings of the He iiλ4686-Å emission line. By detecting weak absorption features from the secondary star, we find its radial velocity semi-amplit...
