Morphology and peculiar velocities of radio sources in rich clusters of galaxies

Data are examined pertinent to a test for correlation between the peculiar velocities and the radio morphologies of radio sources in rich clusters of galaxies. The significance of the test is presently limited by the small amount of data on 'classical double' and 'wide tail' structures in rich clusters, but models wherein distortions from the 'classical double' form increase with the peculiar velocity of the parent galaxy are marginally favoured.
