Abstract:
We present results of a program of optical spectroscopy of radio
galaxies in rich clusters. Redshifts are reported for 268 radio
galaxies or close companions in Abell clusters and 36 objects which
turned out to be foreground or background objects. Absolute line
strengths are also reported for the 3727Å [OII] line and the
[NII]/Hα complex. We find no evidence that the radio activity in
our sample of mostly FR I radio galaxies is associated with
emission-line luminosities above those found in "normal" galaxies of
the same absolute magnitude and optical type. We also find that the
radial velocity differences between radio galaxies and the cluster
mean seem mainly to be a function of galaxy absolute magnitude rather
than radio properties.
