Abstract
To investigate the nature of the radio sources and their associated galaxies in rich clusters of galaxies, observations have been made with the Cambridge One-Mile telescope at 408 and 1407 MHz of the 25 sources in the 4C catalogue in the declination range 20° to 40° which lie in Abell clusters. The results of the observations of 16 of these sources are presented here in tabular form and as contour maps; finding charts are also given for the hitherto unidentified sources. The results of the observations of the remaining nine sources in the sample have been presented elsewhere. Observations of five of the sources with the 5-km telescope at 5 GHz are also presented. The main conclusions which can be drawn from these observations and those of four of the remaining nine are discussed briefly.
