Abstract: | Gamma ray astronomy provides a powerful tool for searching antimatter in the universe; it probably provides the only means
to determine, if the universe has baryon symmetry. Presently existing gamma-ray observations can be interpreted without postulating
the existence of antimatter. However, the measurements are not precise enough to definitely exclude the possibility of its
existence. The search for antimatter belongs to one of the main scientific objectives of the Gamma Ray Observatory GRO of
NASA, which will be launched in 1990 by the Space Shuttle. |
