Scientific paper

Results are reported from a 21-cm search for foreground-galaxy absorption in four radio-loud QSO-galaxy pairs. Data obtained using the Nancay radio telescope during 1985-1986 and the A configuration of the VLA during March-April 1986 are presented graphically and compared with optical (390-750-nm) spectroscopy and images obtained with the Faint-Object Spectrograph and camera at the Cassegrain focus of the 3.6-m telescope at ESO during September 1986. Absorption at redshifts consistent with optical detections of Na I or Ca II is found for PKS 1327 - 206 and PKS 2020 -370 and characterized in detail, but no close correlation between the absorbing-gas features in the optical and at 21 cm is observed. The present observations are shown to be in agreement with previous 21-cm emission studies with regard to the extent of the H I disks.
