| الوصف: | The 21 cm hydrogen line is considered a favourable frequency by the SETI programme in their search for signals from potential extra-terrestrial civilizations. The Pioneer plaque, attached to the Pioneer 10 and Pioneer 11 spacecraft, portrays the hyperfine transition of neutral hydrogen and used the wavelength as a standard scale of measurement.Although this line would be universally recognized and is a suitable wavelength to look for radio signals from extraterrestrials, the presence of ubiquitous radiation from galactic hydrogen could make searches a little difficult. In this paper we suggest several alternate standard frequencies which is free of interference from atomic or molecular sources and is independent of any bias. Comment: 5 pages, 5 equations |
