High-resolution observations at 3.6 cm of seventeen FR II radio galaxies with 0.15<z<0.30

We present high-resolution VLA observations at 8.4 GHz of the seventeen FR II radio galaxies with 0.15 < z < 0.30 and theta(LAS) < 190 arcsec from the sample of Laing, Riley & Longair, together with 5-GHz MERLIN observations of one source. Jets have been discovered in 3C 20, 4C 14.11, 3C 234 and 3C 436, and well imaged for the first time in a number of other objects; the fraction of objects in the sample with definite or probable jets is 76 per cent. The properties of the hotspots of the objects and their implications for models of radio sources are discussed.
