Abstract

Forty radio sources have been observed for the presence of the hydrogen recombination lines 126", at 3248·708 MHz and 127", at 3172·864 MHz with a 6' arc aerial beam and a receiver with 48 channels of 37 kHz bandwidth each. Detections were made in 34 sources, all of which were either HI! regions or optically unidentified thermal sources.
