Scientific paper

ROSAT HRI data for four rich clusters of galaxies at redshifts of 0.5 that contain radio sources are presented. One of the clusters, 53W080, is detected at the 5.2 level; 53W076 is marginally detected at the 2.7 a level; and the other two clusters, 1130+34 and 1245+34, have interestingly low upper bounds on their X-ray luminosities. The X-ray emission is unresolved and could originate from either the hot intracluster medium or the radio source. A comparison of the expected and observed X-ray luminosity of 53W080 suggests that the X-ray emission from this source is produced by the active galactic nucleus (AGN).
