X-ray and radio continuum observations of the bimodal cluster A3528 in theShapley Supercluster are presented. From a ROSAT PSPC pointed observation wefind a marginal tendency of the intracluster gas to be hotter in the regionbetween the two subclusters. This effect can be interpreted as the signature ofinteraction of the subclusters. We infer that the centres of the subclusters inA3528 will meet within a few 10^8 years. In continuum observations at 20cm andat 90cm with the Very Large Array we find four galaxies having radio emission.One of these galaxies shows a head-tail structure suggesting a motion of thegalaxy through the intracluster medium. The radio tail shows an imbalancebetween the thermal pressure of the intra-cluster gas and the pressure of therelativistic electrons.Comment: 8 pages, postscript file including 7 figures, accepted for  publication in M.N.R.A.
