Scientific paper

A search for the tritium hyperfine line at 1516 MHz from 108 assorted astronomical objects, with emphasis on 53 nearby stars, was conducted in June 1983. All stars within 20 light-years visible from the 26-m telescope at Hat Creek Radio Observatory were examined using 256 4883-Hz channels. Twelve stars were also examined using 1024 76-Hz channels. The wideband- and narrow-band-channel observations achieved sensitivities of 5 - 14×10-24W/m2/channel and 0.7 - 2×10-24W/m2/channel, respectively. No detections were made. The tritium frequency is highly attractive for SETI work.
